Revenge:
The problem is that some people have already been seeking revenge against America, Christians, Europeans, etc.
Exit
So, yes, try to get out of wars.
Quietly
Yes, you should generally try to take out leaders more quietly. Trump was probably too loud. Control Freak Lunatics lie to Trump too much. The swamp have been stopping Trump to an extent. There is an internal struggle with the stay behind networks in U.S. government. So, Trump gets excessive amounts of bad intel, etc.
Trump Tech
I would hope that Trump has had some special technology prior to 2015, prior to when he started running to be the 45th U.S. President in 2015. I would hope that a billionaire like Trump would have enough money to at least try to network with smart people around the world who knows about politics, history, psychology, culture, religion, logic, philosophy, health, business, etc. I'm not saying that Trump knows everything. Trump does not. I don't everything either.
Trump Intelligent Communities
But I would hope Trump could have bought some computers that did not have spy chips in them or backdoors or remote access or other things. I would hope Trump had the time since like the 1980's to begin trying to understand the world. I would hope Trump had enough time to be able to distinguish between truth and deception.
Bad Intel
Like, I would hope Trump would be able to have intelligent networks that he could draw from and compare with what he gets from the Pentagon, etc. I don't know how much Trump knows. It is possible that Trump does not know what he needs to know. From my perspective, it has appeared as if Trump made too many bad choices already. I hope I am wrong about that. All we can do is try our best to tell Trump what he needs to know as much and as often as we can. But at the same time, war is complex.
Complex Situations
But you can't just make these things go away. Some people will hate America no matter what. In other words, you cannot please some people. Some people are trying to seek revenge. There is nothing you can do to stop everybody from what they believe.
