Well that and the weird sniffing thing, public speaking gaffes, public walking gaffes, zoning out, unable to debate, got wrangled in by the Easter Bunny, exit of Afghanistan, Inflation rates, an Act that increased Inflation called Inflation Reduction... There's tons of reasons
Well, maybe Reagan when he told dude to tear down that wall... The people on the other side of the wall weren't doing so well & continued situations "could" have led to catastrophic losses... Maybe considerable to genocide
Let me see if I can expand your information, so that you're on topic for the Meme.
Russia Invaded Ukraine (after 8 years of conflicts after Ukraine ousted their leader for wanting to become more involved with Nato), Biden pushed 127 Billion directly to fund Ukraine's impossible "defense" - when part of that defense is Nazi People. That's bad on Putin & Biden & the Ukraine.
Trump Invading Iran - Good, because of 47 years of Iranian Leadership funding various terrorists that have spilled blood on innocent people for 47 years. Literally my entire life - Iran has been doing that.
Trump PLANNING of that Invasion - not good. Continued Peace Negotiations are useless. Conflict is continuing to keep petroleum & products made of petroleum high in price - which impacts everyone. There's no reason this entire thing wasn't wrapped up in 60 days - unless you follow the money & realize everyone invested in oil is making money hand over fist.
I agree about genocide - but none of the war situations under presidents listed in the meme had to deal with anything close to genocide. Iranian People aren't on the brink of genocide, Ukrainians - not close to genocide numbers, Iraq/Afghanistan... Not close to a genocide situation. The closest thing to a genocide anytime recently - was Palestinians & that wasn't US Presidents directly impacting stuff.
