The rest of your post is nonsense. Exporting Western commercial products isn't exporting Western "culture." Nor did Bush claim that anything more than a general desire for freedom motivates mankind. He may or may not have been right about that, but if he was or wasn't, liberty is hardly an aspiration unique to the West.
The problem with Western Civilization is that it doesn't believe in itself anymore, not that it's too aggressive in advancing its agenda.
It might have been around 1967 that Western Living Culture was devoured by Western Golem Culture.
