Yeah, that might be a plausible answer to 1, perhaps even to 4, but really not to 2 and 3.
If I were to dive into this statement more serious, I could say something about the already considerable French militairy power and their involvement, more unilaterally than not, in various conflicts, or I could also say something about the fact that Trump expended the militairy budget. But I think I'll just accept the joke for what it is for the next two years. Who knows, perhaps even six.
