> Russia didn't invade Ukraine

Russia invaded in 2014 and the conflict stabilized (but didn't stop) in 2015.

In the meantime, the Syrian civil war was raging on.

Similarly, if we ignore all the events in the prelude to WW2, the world was a very peaceful place. According to Hoover, Roosevelt was a threat to world peace, not Hitler.

I'm not implying anything with the analogy, I'm only trying to illustrate that the world was not peaceful between 2016 and 2020, despite the president's efforts.

Perhaps if we had gotten 2 consecutive terms, it might have provided more long term stability.
