Nope, the War Powers Resolution gives the president broad authority to respond to an active attack on the United States (which makes sense). But it does not allow the President to unilaterally start an aggressive war against some random country without Congressional approval.

Not that we live in country where laws or the Constitution matter much right now. It's theoretically possible that some people might someday be prosecuted for breaking laws or violating people's Constitutional rights. But even there, I world expect that many of the law breakers will simply be pardoned.
