If you are concerned with how Oman spends its money, then write that post. Are you paying taxes in Oman? How does it effect you? Are you hearing news reports about Oman starting wars? How many military bases does Oman have worldwide vs. the US?
The point here is that values in America are seriously skewed.
The US military budget is indeed a HUGE problem for the entire world. War is the biggest export of the US, and Americans are programmed to believe this is somehow a good thing or even "not that bad".
Oman isn't toppling governments on its own, but the US is certainly storming into nations on baseless grounds and destroying civilizations so private corporations can go in and "rebuild infrastructure" to make more money.
The number of dollars the US spends on the military FAR outweigh that of smaller nations, and those dollars COULD go towards helping humanity. It's obscene and dishonorable.
Justifying it is part of the problem.
I don't care about Oman, but I thought that you cared about military spending, which is why I brought Oman up.
I do agree with you that the values are skewed. If I look at the full budget (this article is a couple of years old, but still close), I don't see how much we pay on the military as an issue, but more in how little we pay for education:

Money isn't going to education because it's going to the military.
Money isn't going to eradicate homelessness because it's going to the military.
Money isn't going to building community gardens because it's going to the military.
Money isn't going to senior citizens because it's going to the military.
Money isn't going to building sustainable housing because it's going to the military.
...and on and on.
