US briefly deploys 2 warships to a disputed South China Sea shoal after Chinese collision

What is the american navy doing there? Yankee go home.
Read the article, but I'll write this for the benefit of those that don't. The waters in question are claimed by multiple nations. The Philippines is one of these and is a US ally. Additionally, the US routinely sends vessels through international waters to exercise those rights as agreed upon by the international community and refute bogus claims.
So that's what the American navy is doing there, and I'm sure they'll go home when their mission is done, and the next will take their place :)
I’m sure the Philippines disagrees
And Taiwan
