That is a good question, so let me answer it with one. In view of the fact tht we are not waging this war against a specific named nation; and. in view of the fact that we are fighting against several bands of butchers from several different nations in several different locations around the world, tell us specifically against whom Congress would declare said war?
Or are you for our troops tucking their tails between their legs letting those butchers run wild all over the world, in cluning in the United States, because we don't have a special rogue nation to declare war on?
... including in the United States ....
To my knowledge there are effectively 2 war powers resolutions currently in force.
The first one names "those nations, organizations, or persons he determines planned, authorized, committed, or aided the terrorist attacks that occurred on September 11, 2001, or harbored such organizations or persons".
The second one names "Iraq".
So that is, literally, the answer to your question. My earlier point stands, nowhere is it written that war can only be declared against nation-states. Indeed, we are living through a counterexample.
Or are you for our troops tucking their tails between their legs letting those butchers run wild all over the world, in cluning in the United States, because we don't have a special rogue nation to declare war on?
Wait, what?
No, I am not for that thing you said.
