We must decide whether aiding and abetting under 18 U.S.C. § 2 is a separate offense from, or a different theory of liability for, the substantive offenses of alien smuggling and transportation of aliens in violation of 8 U.S.C. § 1324.
Odilon Garcia appeals his conviction on four counts of alien smuggling and transportation that also charged him with aiding and abetting. He maintains that the indictment was duplicitous because the two have separate elements and thus are separate offenses, requiring the government to elect between them or the district court to give a specific unanimity instruction. Following Supreme Court and our own precedent, we conclude that aiding and abetting is not a separate offense from the underlying substantive crime, but rather a different theory of liability for the same offense. Accordingly, we affirm Garcia’s conviction on all counts. 1

In the early morning hours of January 15, 2003, four Border Patrol agents re *818 sponded to a sensor alert that had been triggered on a little-used road not far from the Mexican border. The agents intercepted two vehicles, one following behind the other. When the agents ordered each vehicle to stop, numerous individuals, later determined to be illegal aliens, jumped out and attempted to flee. Rather than come to a halt as ordered, the driver of the second vehicle turned his truck around and drove back down the road in the other direction. Agents gave chase, and eventually came upon the vehicle, abandoned by its driver on the side of the road and teetering on the edge of a steep ravine. There was an individual in the cab of the truck who had to be helped out. Garcia was found in the area, injured and walking in a daze. Keys were found in his pocket that unlocked the abandoned pickup and started the ignition.
A federal grand jury returned a four-count indictment charging Garcia with bringing two undocumented aliens into, the United States for private financial gain, in violation of 8 U.S.C. § 1324(a)(2)(B)(ii), and with transporting them within the United States, in violation of 8 U.S.C. § 1324(a)(1)(A)(ii). The indictment also charged Garcia with aiding and abetting with respect to each count, in violation of 18 U.S.C. § 2.
Garcia filed a pretrial motion to dismiss the indictment on grounds of duplicity, but the matter proceeded to trial without a ruling. Garcia also requested a specific unanimity instruction that would have required the jury to agree, for -each count on which it found Garcia guilty, whether he was guilty as a principal or as an aider and abettor. The district court declined to give such an instruction, reasoning that aiding and abetting is not a separate and distinct offense but rather a different theory of liability for the substantive offense. Standard instructions on aiding and abetting and on unanimity were given.
The jury found Garcia guilty on all counts. Garcia timely appeals.

The parties dispute whether our review should be de novo (as it is for the question whether counts of an indictment are duplicitous,
see United States v. Bryan,
HI
Simply put, Garcia’s position is that the elements of aiding and abetting are different from the elements of smuggling or transporting an alien because the latter is a general intent crime while the former requires specific intent.

This being so, in his view, aiding and abetting is a separate offense because the presence of different elements means that the offenses are different. For support, Garcia relies on
*819
United States v. Ramirez-Martinez,
Ramirez-Martinez
is not, however, dis-positive. As it happens, the defendant there was also charged in a different count as an aider and abettor with bringing to the United States an undocumented alien for financial gain in violation of 8 U.S.C. § 1324(a)(2)(B)(ii) and 18 U.S.C. § 2. In that connection we observed that “[sjeetion 2(a) of Title 18 does not define a separate offense but rather makes it unlawful to aid or abet another in the commission of a substantive offense.”
Ramirez-Martinez,
More importantly, there are fundamental differences between
attempting
to commit a crime, and
aiding and abetting
its commission, that distinguish
Ramirez-Martinez.
In an' attempt case there is no crime apart from the attempt, which is the crime itself; for this reason the defendant must act with the purpose of violating the immigration laws even though that mens rea is not required for the substantive offense. In the context of aider and abettor liability, there is a single crime that the defendant is charged with committing; he could commit that offense by directly performing illegal acts himself, or by aiding, abetting, counseling, commanding, inducing, or procuring the commission of the offense. Whichever, the defendant (if convicted) is liable as a principal.
See
18 U.S.C. § 2(a) (“Whoever commits an offense against the United States or aids, abets, counsels, commands, induces or procures its commission, is punishable as a principal.”). Thus, unlike the mens rea for attempts, an aider and abettor’s intent regarding the substantive offense is the same intent required for conviction as a principal.
See, e.g., Gaskins,
Of course, to prove liability as an aider and abettor the government must establish beyond a -reasonable doubt that the accused had the specific intent to facilitate the commission of a crime by someone else — and this is an “element” that need not be established for conviction on the underlying offense. However, as the Supreme. Court pointed out in
Schad v. Arizona,
We believe that aiding and abetting as charged in this case falls naturally within the
Schad
analysis. Aiding and abetting is simply one means of committing a single crime. Indeed, we have often referred to aiding and abetting as a, theory of liability.
See, e.g., Gaskins,
Garcia postulates that this creates a unanimity issue, but we disagree. In this case, the jury was properly instructed on the elements of the substantive offenses and for aiding and abetting liability. The general verdict reflects agreement that Garcia committed the particular offenses of bringing illegal aliens to, and transporting them within, the United States. It does not matter whether some jurors found that he performed these acts him-sélf, and others that he intended to help someone else who did, because either way, Garcia’s liability is the same: as a principal, for committing the acts charged.
Accordingly, the indictment charging Garcia with the substantive offenses of smuggling illegal aliens in violation of 8 U.S.C. § 1324(a)(2)(B)(ii) and 18 U.S.C. § 2, and transporting them in violation of 8 U.S.C. § 1324(a)(1)(A)(ii) and 18 U.S.C. § 2, was not duplicitous. Aiding and abetting is not a separate and distinct offense from the underlying substantive crime, but is a different theory of liability for the same offense. For this reason, the government had no obligation to elect between charging a substantive offense and charging liability on an aiding and abetting theory, nor was the district court obliged to give a specific unanimity instruction.
Affirmed.
Notes
. For the first time on appeal, Garcia raises a challenge to his sentence under
Blakely v. Washington
, — U.S. -,
. For aiding and abetting liability the government must prove four elements:
(1) that the accused had the specific intent to facilitate the commission of a crime by another, (2) that the accused had the requisite intent of the underlying substantive offense, (3) that the accused assisted or participated in the commission of the underlying substantive offense, and (4) that someone committed the underlying substantive offense.
