Being isolationist is stupid.
Understanding how the world works and making sure that no one does anything because you will level them is also a good strategy.
Don't confuse isolationism or interventionists for being good and evil when it is more nuanced.
Being isolationists never go well for the US
Nice job completely ignoring the part where we are literally occupied by illegitimate puppet government of a deep state who is running a fake democracy as they cheat the vote while they are flooding the country with a literal army of illegal invaders.
It isn't isolationism to point out that the occupation puppet govt that is our enemy will just fuck up any foreign war in the worse way possible.
Or that we have too many enemies at home to project power outwards
Rather than isolationsim, it is a "I am weak and sickly-ism"
Not because American tanks and air planes are bad.
But because those war machines are at the hands of traitors and usurpers, or rather, their bootlickers. Because we all know the demonrats will never actually bother serving in the military.
And the only ones who aren't traitors, happen to be incompetents.
As much as you wish otherwise. Guns don't kill people, people with guns kill people. And so long as the people with guns are serving an illegal occupation govt that is oppressing the populace while on the cusp of civil war... well, they won't do a very good job going out there are killing foreigners like you want.
