This is all really trivial and only really even true during relative peacetime. As the imperial blocs approach general conflict and subsequent intensification of class struggle these appearances will easily melt away and all competing interests are subordinated to the national interest. If the tools at the disposal of liberal democracy are not enough to contain and subordinate the class struggle happening at the time to the national interest, the bourgeoisie will easily abandon all those illusions and resort to fascism. It's really going to depend on the strength of the labor movement to come. The bourgeoisie of the west has enjoyed a weak labor movement since the end of WWII but that's a trend that may change as we approach the third world war.
