>>1167617The president does not have the power to make war, a president has to inform congress of any military actions within 24 hours of committing them. Large scale actions require congresses approval before enacting them, so at best Trump could send a small expeditionary force to Ukraine, which congress would probably recall or force to provide aid to refugees only. I think both Trump and Biden would handle the conflict the same, by using covert action and funding to Ukrainian rebels, just like what was done in Afghanistan in the 1980s. The idea is to make Ukraine a Vietnam situation for the Russians, though there is no telling how this will go. Of course the CIA could always cause a coup in Russia or assassinate Putin, like what they normally do.
Overall I wouldn't worry about the war in Ukraine, unless you are Ukrainian or Russian, you wont feel much of an effect. The status quo will most likely return. As for Taiwan, I doubt anything will happen as Xi Jinping has to deal with CCP elections sometime during the 4th quarter of this year. His long time rival Jiang Zemin is likely to defeat him in the election, Jiang has control over much of the military and political class, though it's hard to truly know who has more power. The Chinese military is at a very weak point due to party negligence at all levels, they would be unable to defeat Taiwan before the elections, thus Xi is unlikely to invade until he's reelected. Jiang is supported by the US government and CIA, thus if he wins he'll probably avoid the Taiwan issue, (he has also ordered assassination attempts on Putin so he's not gonna be friends with Russia). The CIA is guaranteed to be working behind the scenes to stop Xi's reelection.
