So if China installed puppet dictators in Canada & Mexico & then welcomed them into a military alliance that has been hostile to the US & cut of US access to factories & infrastructure owned by US companies in both countires it would be US aggression to do anything about it?

This is like people calling Iran the aggressor because "look how close they put their country to all of our military bases."

The US has a more aggressive foreign policy than any country in the world, but somehow it's never the US which is doing anything wrong. Take the patriotic blinders off.
