Well we could devote those resources to solving the problems they are criticizing maybe. It would improve the lives of USians and undercut the arguments being brought up.
Spending billions to tell other countries that more infrastructure is actually bad is probably counterproductive and wasteful. Like how we spent money to kill Filipino people by telling them to avoid the Chinese produced covid jab.
I don’t think China wants to be the enemy of the US. They are the largest trading partner of the US. They seem genuinely interested in cooperating and bettering their own society. USians seem to be the ones bent on enmity. The US apparently thinks building infrastructure and developing the economies of other nations is ‘malign influence.’ The US killed citizens of allied nations through propaganda to ensure they wouldn’t become friendlier with China, who was offering them vaccines while the US and Europe were hoarding their own.
The US sees ‘being a large country and having influence’ as threatening, there’s no way to peacefully coexist with a country that sees everyone else as a threat by default.
