I do not how much of it, but obviously it is more narcissism than any president of the United States is supposed to have, so they can direct their republic to a good future.
If you asked me, Trump with his peace-making speech is not only trying to appeal to people living in other countries or leaders of other nations, the way he uses this speech is order to try tk convince those who are not in favor of using tax money to fund wars, while at home there are people do cannot afford to pay for shelter and suffer in the winters, or those who cannot afford some medicine to take care of themselves.
It is a left wing speech, but twisted to bring people to vote for a man who obviously has nothing to do with left wing policies. It is a good strategy, and will stay as an strategy, since it is obvious Trump won't use that funding to pay for medicine, though.
I dislike Trump as much as the next guy and I think Biden is a much better president and on top of that I think they both should not be the president and someone younger and more fierce should get the job.
However, even I have to admit that Trump was the most anti-war president they had in a long time, everyone else constantly attacked everywhere, even the Nobel Peace prize winner Obama (how the hell did that happened is still beyond me) was bombing kids in Afghanistan while making his speech, that is the corruption of the world, Biden bombed places in the first 100 days of his presidency, he was quick to trigger as well.
Trump is a terrible human, I would not want to be in the same room as him, and he makes me want to vomit whenever he speaks, he is definitely evil to the core, but one good quality about him is that he doesn't want war, and he tries to make peace and that is a VERY important thing in our world, that would definitely be helpful at this moment.
You must have forgotten when we were on the brink of war with Iran and Trump had to be talked down by generals early in his term. Or when he was tweeting direct threats about how his "big red button" was so big to North Korea.
He's also campaigned on attacking Mexico if elected.
