Yes. I'm sure a reasonable way to estimate it could be found based on how capital is tied up in space and time. Local, slow circulating and high constant capital vs global, fast circulating and high variable capital. The latter might be more likely to side with or be subjugated by the empire. China is shifting to the former. (One problem is, that high constant capital firms are often also global.)

However, like in our own struggle, it's not enough to be a class that has a natural interest. You also need to be conscious of that interest to act on it. Consciousness might be forced by rising contradictions. But I don't feel like most of these national factions of capital would join a united front soon. Most of them might turn to open fascism first before they ally with us. It's an important question to explore.

Granted, maybe I'm oversimplifying here. Imperialism vs fascism. Aren't they two sides of the same coin? I'm sure there is a dialectic here. Still the question will inevitably pose itself and not just in Europe: with whom to ally as socialists? A united front against imperialism for national liberation even with factions of national capital? Or a popular front against facism even with liberals and social democrats? Even if either of them is formed successfully, both would try to betray us sooner or later. Or is there a third way ?
