Presidential Wars With No Congressional Declarations

                Under the definitions of war and co-belligerency referenced above, the United States is fighting nine known presidential wars with no congressional declarations in violation of the Declare War Clause. In none of these conflicts has Congress declared war or otherwise by statute or joint resolution made a decision to change the condition of the nation from a state of peace to war.

Pakistan

The United States conducts drone strikes and provides other military assistance to the Government of Pakistan in its wars against Pakistan Taliban or sister insurgents. That makes the United States a co-belligerent without a congressional declaration. Pakistan has also publicly protested United States invasion of its sovereignty with predator drone killings on its soil. It is unclear whether these protests are genuine or politically contrived. The United States military is operating under the laws of war in Syria, and doing things there which would be deemed war if done in the United States by a foreign nation or entity.
