America has already lost, they are just refusing to admit it.
Iran has proven that the mighty American war machine is not so mighty, Iran has not just given Israel a bloody nose but have broken it, the US military is almost at the stage of open defiance to the government, China and Russia are laughing off American sanctions, and the US economy is tanking.
The only thing that worries me is that America is run by a bunch of lunatics and end-times evangelicals, and they could decide to nuke Iran. And then when there is no Russian and Chinese cavalry riding to the rescue and destroying the Terrorist State of America once and for all, nuclear weapons will be normalised (like every other war crime committed by USrael) and we will enter a really, really dangerous era that will surely end in catastrophe and the end of civilisation.
