CNN has an article titled, War Powers Act needs fixing, bipartisan panel says. To quote the article,

The United States needs a new law requiring that the president consult with Congress before going to war, a blue-ribbon panel led by two former secretaries of state said Tuesday.

I may be wrong, but doesn’t that law already exist. It was enacted a few years ago, more specifically, 1787 – The Constitution. It is only constitutional if Congress declares war, not the president. The article mentions this law at the end. The shear existence of this article blows my mind. Wow.
