Israel was signing peace accords with 3 different Arab neighbors under Trump and Iran was being starved financially so it wasn't able to finance terror around the world as it's done under Biden.
Russia didn't invade anyone during Trump's time in office.
Trump was in the process of building the wall but he was obstructed by Democrats every step of the way on that. The border was SO much more secure back then though...the difference was massive.
Iran was being starved financially by various presidents. Obama put strong sanctions against Iran, Bush had banking sanctions. And Trump also put sanctions in place. Iran is still there, Iran helped Hamas to attack Israel.
Israel got attacked by Hamas even with the Abraham Accords that Trump got. The countries that signed the accord were countries that probably hadn't done anything to Israel in a long time.
Sudan, went to war in 1967 with Israel. Didn't participate, just declared war and did nothing. Literally sums up their relations with Israel before 2020. Didn't do anything. After the accords, Israel and Sudan barely noticed each other existed.
Morocco, made deals with Israel before the accords, but they were under the table deals. But mostly it seems that the royal family didn't want to do anything to Israel, but the people were less enthusiastic. Then after the accords, their relationship is pretty much as it was before, only with official recognition of Israel.
The UAE, their relations started to improve in 2010, mostly as an anti-Iranian thing. Israel opened an official diplomatic mission in Abu Dhabi in 2015, before Trump arrived. So, things were already moving towards the Abraham Accords before Trump.
Bahrain, they had relations with Israel from their independence in 1971, a delegation was sent there in 1994 by Israel. Trade missions were opened in 2000 in both countries.
So, Trump didn't really do much, it was either something that had been happening for years, or something that didn't make a difference.
And the reality is that Hamas attacked Israel... his accords didn't change the reality for Israel.
Russia not invading anyone... well... Russia was in the Ukraine during the whole of Trump's presidency. Trump didn't change that.
Russia, with the Wagner Group was increasing its influence and money in Africa during this time.
Russia was building up its financial supplies in order to invade the Ukraine during this time. Just because Trump, in 4 years, didn't see an invasion by Russia, doesn't mean Russia wasn't acting against in a nefarious manner during this period. It just means it wasn't ready. In other words, a coincidence.
The wall... does it work? Nope. Says the dude at the Republican conference where a dude with a wall all across his border property complained about the immigrants on his land.
So.... mostly if you look at what Trump did, it wasn't anything that actually had a big impact. He made it showy, but really, nothing changed anything. NOTHING.
