Define win because I’m pretty sure it doesn’t mean what you think it means.
The only tactic with “almost instant” results would be the US just nuking everything, which A. is definitely not a “win” by any definition, and B. is an insanely irresponsible assumption that there wouldn’t be substantial collateral damage and that’s if you were inhumane enough to ignore the lives of everyone living in the targeted countries to begin with.
Or somehow do you think the US could win a conventional war against three separate countries “almost instantly”, after it took 2 decades to make absolutely no lasting changes in Afghanistan? In which case just lol.
Republicans: categorically awful on every single issue
Democrats: Not that
Babies: waaaah I want a competitive party that matches my opinions on every single issue
Find me one major party in the entire world that matches your personal ideals 100%. Spoiler: it doesn’t exist, unless you happen to be a king or dictator of an authoritarian state.
Two party systems means you have two parties with distinct ethics, and one party winning consistently means the country’s ethics will shift over time in the favor of that winning party. So keep spite voting against Democrats and see where that gets you.
Edit: you know why the Democrats are similar to Republicans on so many issues? Because Republicans keep winning elections.
