NAFTA, NATO, UN, the US pretty much lead the charge to create each of these multi-country groups. There were 2 world wars prior to the US involvement in world affairs, there have been 0 since. I feel pretty confident in saying that America pretty much has the reins of the world. That being said, you underestimate just how horrendous our populace is, we will have Trump until 2024. That is a long time for any nation to endure being called the enemy of our country and treated with such disdain and disrespect, while true enemy nations are treated to hot towel treatments as we kiss their feet for meeting with us. In case you missed it today, Trump literally told an unfriendly nation, who his own intel departments have accused of election meddling (not just Obama's people, but even the people he has installed), that he believes this unfriendly nation over his own countrymen because the unfriendly leader "strongly said he didn't do it." That's so far outside of okay. He might as well tell the CIA, FBI, and NSA agents to pack up shop and shutdown all operations, because they are useless to him.
