The problem for US is that it's already in over its head with what's happening in Ukraine and Israel. At the end of the day, they don't have infinite resources. And as more and more countries join BRICS and realign economies away from the west, the less vulnerable they are collectively.
Yeah but destabilisation operations and general meddling are actually quite cheap, and literally peanuts compared to war. They can afford real many of that as we can observe by the sheer number of countries where they meddle strongly enough to be visible, all at the same time, and constantly.
That only works in countries that are already unstable though. Traditionally, the playbook has been to do sanctions first, create enough discontent, and then leverage it with orgs like NED to create puppet opposition. However, if countries are stable economically, that whole process can't take root in the first place. Hence why decoupling from the west is so critical.
The kind of aggression we are talking about at the moment is american state governments ordering chinese people and companies to sell their assets for pennies on the dollar.
Yes, Mexico is rather vulnerable. It's an annex of the US economy. But it is a sovereign nation. There are american boots on the ground in Perú right now, and the coup government still works with China for infrastructure development. At the very least these investments mean China's export markets are less dependent on the G7. That's real de-risking.
