I would NOT want to get into a land war with China. Army? Thats no joke.
Airforce? That would be bloody.
A naval conflict with china? Uh, yeah, that is a completely different story. That would be a foregone conclusion REAL fast. Building ships ain't like making tanks or planes. You can't hide that. You got ONE place where you can put them out to action: the coastline. Which is right next to that wet area we call the ocean, you know, where we enjoy a 4:1 margin over the REST OF THE WORLDS NAVIES COMBINED. With not only a numerical superiority but also the longest contiguous fighting experience (measured in decades) accrued in the modern world.
Not to be cocky or anything, but there's a reason for my confidence. And not just because I'm ex-Navy: its because we aren't just the ones with the most stuffs, we're also the best equipped and the most experienced. By far.
