Is China the biggest threat?

JJ Sefton writes today at Ace of Spades,

Foreign policy-wise, there are reports that H.R. McMaster might be the next one out the door at the White House. Fake news or real, I'm not a fan of McMustard. I think he's in with the in-crowd in the Deep State. Meanwhile, Putin is shooting is mouth off about doomsday devices and such in an effort to scare the President, but mostly as a reaction, I think to our military moves in and around Syria which Bladder-meer doesn't exactly appreciate. That and our sale of anti-tank missiles to the Ukraine. Also, the fact that our forces wiped out about a hundred or so of his Hessians without breaking a sweat might also have aggravated him just a tad. But, the long-term threat that should be addressed is China; the recent power-grabs by Xi Jinping in China, his bellicosity and what that means not only in the Trump era (long may it reign) but beyond I think is now our number one strategic concern.
