George W. Bush was elected on a platform of no more nation building (and secured his second term in an atmosphere of fear and war), as was Donald Trump. It's very clear that the majority of Americans do not want more war & nation building (the only ones that do, are a contingent of conservatives like McCain and even fewer similar hawks on the other side).
The globalists + military industrial complex go ahead and do what they want anyway, against the wishes of the American public. They've been doing so for a long, long time now. Vietnam was not a very popular war, they did it anyway. The notion of no longer blowing up the Middle East and treating Russia as a villain, was impossible for them to stomach re Trump, so the CIA & fellow globalists (aka the deep state, media, etc) immediately went on hyper attack (oh the consequences of going against the machine).
