Yes, that is more or less correct. My problem is primarily with US weapons manufacturing and military spending. If it could not be shut down entirely, then, all else being equal, it would be preferable for it to be offshored to Europe, or anywhere else, to keep as much as possible out of the hands of the increasingly fascist and beligerant US (not that Europe can be relied on to resist the US, but any barrier is preferable).

In most cases, the main enemy of a poor person of a given country is a rich person of the same country. I believe in following my class interest, not some "national interest" that's typically completely divorced from my own, if not actively detrimental to it. I have no interest in upholding or protecting that "national interest," that "national interest" is really bourgeois interest and the bourgeoisie are more than capable of looking after it themselves.

There are some exceptions, however. Franz Fanon, for example, argued that in developing countries, the gap between the domestic rich and poor is outweighed by the international gap, such that a class truce may be acceptable to resist foreign colonizers. Likewise, the CCP was willing to form a temporary alliance with the KMT in order to repel the fascist Japanese. The USSR opposed strikes in the US during WWII because those strikes would have impaired the war effort against the Nazis.

These exceptions to the general rule of class war only apply when there is a significant, genuine threat to the average person, when the foreign threat is intent on outright extermination. If it's merely trading one set of capitalists for another, then it is not my fight and none of my concern.

Typically, anything that benefits the bourgeoisie, that benefits the so-called "national interest," is bad for me, even if it doesn't harm me directly. Because the more money and resources the bourgeoisie possess, the more power they will be able to wield against me, lowering my wages, making me work longer hours, taking away my healthcare and security. All of these things they are more capable of when they have money, weapons, and resources acquired through imperialist conquest.
