Does a defendant have a constitutional obligation to submit to cross-examination?

At the same time it has been recognized that the constitutional right to testify is not so absolute that it may not be subjected by the state to reasonable restrictions. For example, the right to testify carries with it the obligation to submit to cross-examination. United States v. Hearst, 563 F.2d 1331, 1340 (9th Cir.1977). The defendant is faced with the decision of whether he should preserve his constitutional right to complete silence or put on what may be his only defense and thereby open himself to cross-examination. United States v. Wagner, 834 F.2d 1474, 1483 (9th Cir.1987).
