There is also a good way of saying "we just won't spend this much on military anymore" and the left would be all behind that, would Trump do that? Or is he just want more for the people who bribed him to be there?
If you spend 800 billion on military and lets say that 100 of that goes to spending on NATO, would you cut it to 700 and not help NATO, or would you keep it at 800 and spend it on Warhawk companies in the USA? That's the real question, if we are talking about a cut, which Trump could have done any time in his 4 year tenure, that would be fine and accepted by everyone, this is why it would be a lot better if we just knew what he would do by his first 4 years, if he didn't then nobody would trust him to do it in another 4 years, could be a big lie.
First of all, Trump is a businessman. Do you really expect him to take a stance against these big private defense companies such as Boeing and Raytheon? There is a big difference in what he says in the public, and what he practices in reality. No politician, whether he is Republican or Democrat has the courage to take on sectors such as Pharma and Defense, who are like parasites leaching the American society. Even medications for common diseases such as diabetes cost 10x or 20x more in the United States, compared to the prices in Canada. Trump didn't did anything to relieve this issue when he was the POTUS.
