Notice I said 3 years, not 4. He finished the wars from the previous 20 years and money spent isn't the correct metric. He did not open a new theatre of war but closed virtually all.
Trump invested in industries that were considered dead by Obama, but are critical for national security. Those jobs came back to the US which is why unemployment dropped to where it was. The low unemployment rate is what lead to the wage growth.
The same wage growth that the Fed stated to be their goal to stop. They weren't fighting price inflation, no one cares until it became wage inflation. There are genuine enemies of the people. The metrics show that Trump is not. He brought peace and prosperity to the world because a strong united states is imperative to peace and prosperity across the world. That's not a rose colored glasses perspective. Aside from European leaches, he was almost unanimously loved by citizens of the world for the stability he brought. The only instability was in the media.
