You are confusing Capitalism with foreign policy.
> Why not?
Where do you think all this anti-US violence comes from?
Empires have never fared well once they fell from power with the exception of the British who were geographically isolated and had very powerful allies.
Simply because the bloodshed caused by US foreign policy mostly occurs on foreign soil doesn't mean it will stop just because the US is no longer an empire.
> I think it's hard being at the top and maintaining global order. You get blamed for everything and you get credit for nothing.
The US actively instigated violent revolutions, torture, and abuses in other countries. Pretending that is "part of maintaining global order" is absurd.
The pillars of what the US is credited for is something half the population actively rebels against (globalism, free trade) and were achieved in spite of the popular will domestically.
Simply because I believe a certain technique should be verboten doesn't mean I ignored credit for the US's successes.
