You just need to target the establishment (i.e. de-nazify the Five Eyes) and create internal fighting, supporting one group over the other. Internal strife will have them aim their nukes at each other. Divide & conquer - very effective strategy from their own playbook.
Or continue on the current path of no direct interference, focusing solely on the economics; soon they'll run out of money to finance their wars and military, especially with the increasing domestic unrest.
I think option #2 may become unlikely because the US sees this as already happening, hence jumping to initiate war.
This is actually a sad reality of agriculture in many Western countries. Italy has a large Indian slave labor workforce employed in agriculture. Canada has ~40% and USA ~70% of agricultural workforce composed of slaves from Mexico and Central America who come here seasonally, working well below safety standards and minimum wage. Nobody wants to talk about it or fix the issue because the truth is: if it wasn't for this slave labor, the $2 loaf of bread in the supermarket would cost $9.
