However, if the War Powers Act is amended to cut off all funding for a conflict that does not comply, then that is simply Congress using the power of the purse in a perfectly appropriate manner. My understanding is that the House just passed such a provision.
That is questionable.
This is a way for Congress to never have to declare a war and to still be able to pull funding at any moment they want.
It gives them an unconstitutional legal strategy for never having to commit to any policy along with the President and to be able to defund it the second the polls go against the President.
Any Congressman can then claim after the fact that he was either for or against the war depending on its popularity.
This is not the way the Framers intended it and not the way they wrote it.
