North Korea has been a crisis since I've been alive. The current regime presides over a humanitarian nightmare, they are posturing in a way that suggests they will try to start a world war, and instead of clamping down on them and treating them as the existential threat that they are to our allies (South Korea and Japan, namely), our Cheeto-in-Chief is giving Kim photo ops and telling the world how they "fell in love." Fucking gross. And dangerous. And it's gotten worse under Herr Drumpf because now we're just turning a blind eye to the missile tests, pretending that it's not happening; this gives cover to Kim to ramp up his efforts to further fortify his stranglehold on the region.
Yes, we need to intervene in Syria for myriad reasons. Assad uses chemical weapons against his own people. The Kurdish people were promised statehood by the United States, France, and Britain after the first World War under the Treaty of Sevres, which has still gone unfulfilled. They lost over 11,000 of their people assisting the United States in the fight against ISIS, where the US only lost a little more than a dozen. They have fought beside America for decades upon decades, in hopes that the United States would live up to their promises and Ferret-Hair pulls the plug and abandons them for SLAUGHTER to appease yet another authoritarian (Erdogan).
When Russia annexed Crimea, President Obama lobbied to have Putin's Russia expelled from the G-8, and we backed the Ukraine's efforts to push back against pro-Russian infiltrators in their own government, much to the chagrin of folks like Manafort, Parnas, and Fruman. Don't worry though: yet again the Orange One went and fucked it all up so his buddies could get rich off of the Russian Oligarchy trying to annex the rest of the Ukraine in a tit-for-tat that included funneling Russian money illegally into Donald's pockets.
The ultimate point here is that Donald tRump makes the world, and America, less safe and doesn't give a shit as long as his bank account gets bigger.
