I think the Democrats know exactly what they're doing.
They actively and intentionally work to reduce American dominance on the global stage. It is the all-but-stated goal of leftists here and abroad - to bring uppity America down to the level where they are forced into the marxist global state.
Excellent cartoon!
And you are right, the Dems are doing it deliberately, trying to wreck the economy of the US and diminish our influence globally.
