Comment: Nor did Clinton or Obama.

Clinton did the first cruise missile kills in Iraq and Afghanistan and Obama gets credit for intentionally killing the first US citizen by drone missile attack.  

No trial; no charges, just Presidential 'findings'.  

That applies to all of the last four (4) Presidents.  Although George W. did get the Senate to buy off on Gulf War II.  

And Obama used that to justify all his attacks on Yemen, Libya, and Syria.
