"The USG is the US federal government?"
Yes.
"I don't know the difference between US federal and US state governments."
States are like countries. The federal government is like the EU.
"I don't know why you hate Obama."
Obama vowed to reverse the aggressive wars overseas, to close Gitmo, and stop torturing people. Instead he made them all worse, and assassinated an American child with a drone strike. I don't particularly hate him. He's just one more traitor that needs hanging.
"...I hope the US fleet will be stationed in Taiwan."
If there is any good thing for freedom and prosperity the USG can do, it will do the opposite, to destroy freedom and felicity of the people of the world. It is an evil organization, dedicated to the supremacy of one group over all other peoples, which it seeks to render dead or enslaved. If you think it has done a good thing, either the people have forced it, or you have been tricked.
Thanks!
