The reason they haven't declared war is, quite simply, that the administration wants to be the one to make the decision as to war and peace. To them, the war option is their little ace in the hole, to be laid on the table and retracted entirely at their convenience when it suits their political purposes - in total opposition to the spirit of the Constitution.
You have absolutely no idea what you’re talking about. The Geneva convention that we formally become a treaty member to about 60 years ago does not bend to "whatever rules of war Congress wants for a given war". I really can’t take extraordinary claims seriously when they come from someone who doesn’t even know this.
I’m no authority on this, but I know better than to read a few kook editorials from fringe groups and start parroting them as if I’m now an authority and know something that the establishment hasn’t figured out. It’s not a grand conspiracy, the whole world isn’t more corrupt than you, and you’re not exceptionally brave, brilliant or insightful. This is an imperfect world, another tricky day, and this war is as just and legal as about any other that we’ve conducted. I’ve got some very important things to complete today. My apologies for not having more patience in this discussion. Best regards.
