the US armed forces gaining experience by butting in the conflicts of other indenpendent nations?
Actually, before there were conflicts...US Armed Forces have been continously conducting military exercises between allied nations. i.e. Tandem Thrust, Foal Eagle

Military exercises are usually performed four times a year.

All of these military exercises are unheard of (with the exception of the amphibious group landing in Cavite) through the use of...

without the means of being able to deploy those outside of China (through a naval fleet).
the US Naval Fleet.

That makes me agree with mazdamazda regarding the use of naval fleet.

Let me share my experience with Taiwan and China conflict.

On our way back from conducting multiple military exercises in Western Pacific region, the C.O. announced that we are turning back to scold China and N. Korea because of their missile testing over Taiwan airspace. As soon as the Carrier's presence was seen in Yellow Sea, China and N. Korea stopped playing with their missles, phakers...bring it on.

Our stay at sea was extended for a week, we're finally headed back to Naval Base in Japan. We all said to ourselves "p*#$$ inang China and N. Korea yan, uumpisahan manakot wala naman palang gagawin amf! nasayang lang ang isang linggo mga ayuf!"

N. Korea has the farthest range in terms of missile, it can reach Hawaii. The only time that they will stop developing long range missiles is if the US gives them aid. Wow, responsibilidad pa pala ng US ang N. Korea and yet, US are taking the blame on interfering with conflicts around the world.

edit: oh yeah, US agreed to give N. Korea the aid they wanted and among other things.
