Where Chinese aggression = China trying to police its own area?
Maybe some Chinese carriers should have helped tamper US aggression all those years in Banana Republics, Mexico, Panama, South America, etc...

The same Philipines the US occupied and used as a colony (and neo-colony) and the same Japan where the US nuked civilians and had the country under supervision (it's army) etc. post-war?
Not to mention this is not actually "stationing their ships in the Philippines and Japan" (which the US does all the time, literally, in their harbors), but having disputes over some sea territory.
The US has not had any ships stationed in the Philippines since the early 90s. In response to local demand the base there was closed.
Granted, parent misspoke of China as stationing ships in those places, but your argument is similarly absurd.
The issue at hand isn't China's possible hostility towards neighboring countries centuries or decades ago but rather their fairly hostile posturing with regards to territorial claims today.
With regards to your second point, from what I've read the Philippines and Japan view China's currently expanding territorial claims to be an aggressive military expansion. I'm not sure the act of US ships being present in the harbors of Japan and the Philippines is analogous to China's military activities in the South China Sea and Western Pacific, particularly as I assume both of those countries have given explicit permission to the US Navy to enter their territorial waters.
It seems like the ships are getting good use in the current climate. Carriers are the best choice of weapon in an asymmetrical war against terrorists. Terrorists can't target a Carrier Group, but Carrier Groups can bomb them all day, every day nearly perpetually.
