Ron Paul's Liberty Defined 9

In my latest reading of Liberty Defined: 50 Essential Issues That Affect Our Freedom, Ron Paul talked about how the United States in 2009 spent 46.5 per cent of the world's military expenditures, then he asks, "And how much of the rest of the world's spending is due to nations protecting themselves against the United States as the perceived threat?"

Ron Paul elaborates on page 257: "Now, most Americans can't even conceive of other countries believing the United States to be a threat.  And yet, ours is the only government that will travel to far distant lands to overthrow governments, station troops, and drop bombs on people.  The United States is the only country to have ever used nuclear weapons against people.  And are we surprised that many people in the world regard the United States as a threat?"

Is there truth to this?  I don't think that we are the only country that has overthrown foreign governments, sent troops, or dropped bombs, for (if I'm not mistaken) the Soviet Union did that.  Nowadays, other than us, there does not appear to be a massive nation that does these things, and yet terrorist groups such as Al-Qaeda certainly cause destruction and mayhem (as Ron Paul knows).  But I can understand Ron Paul's point that the U.S. is a looming presence in the world, and I'd say that has been for good and for ill, as far as other countries are concerned.
