This leads to US competitors retaliating, resulting in political friction, trade wars, and these , as history shows, can eventually lead to hostile new power blocs emerging, and eventually nation states are impelled to escalate todays proxy wars into barbaric world wars where the major powers, armed to the teeth, directly confront their rivals. The workers have to be vigilant and and organize against these deadly tendencies of capitalism. Nationalists, left, centrist and right, will find ways to rally workers away from their real class interests and instead directly around the bosses flags. So much for the 'peace' credentials of the Green Party. The workers interests are hostile to the bosses interests.
Workers can effectively organize politically and economically to fight their class battles.
But the ruling class is slick and and has laid down many political and ideological minefields to keep workers passive, divided. Workers, kept atomized and chroloformed behind a boss dominated voting booth are impotent. Organizing our class movements from below based on a policy of class against class, we develop real power in practice . We can eventually build up a Internationalist Working Class Party that will unite the class struggles for workers rule, production for human need, not for sale and profit.
