You are right of course Pepokish, money is money.
Still, it seems kind of odd to have to wonder about 5$-bills being flushed while certain people insist that flushing 100$-bills is unavoidable and not even "flushing".
I'd rather see those 100$-bills saved for something useful and contructive. In that case, flushing the occasional 5$ every now and then would not be a problem at all.
(That toilet-analogy is pretty weird here.
)
Military funding is quite large, but what do you propose to do about it? If we pull in the troops, all the blood, sweat and toil would be wasted.
I sort of agree that the whole Iraq-situation is stuck at a point of no return. Not that I believe it can be "won" or anyting but simply withdrawing isn't a decent choice either.
Still, we are not really talking about a unique situation here where a nation is stuck in this "unavoidable" war and thus has to fight it out by any means possible - that would be the second worldwar -> skyrocketing military expenses due to mobilization (~ten-twenty fold).
While the base-cost of the US-military in the past ten years has increased from ~300 billion $ to ~500 billion $, the Iraq and Afghanistan wars added merely another ~200 billion $/year to actually activate and use that huge army.
While that certainly sounds a lot, just picture that first, the general investment-increase on the military was as high as the cost of the war: Somebody is considering a much larger military a generally needed thing for whichever case there may come besides the current war.
And second, 300 billion $ are already a vast, vaaaast military budget or in other words:
Since the second worldwar US-military expenses have always been way above 30% of the whole worlds investment in warfare.
Also, it has always been around or way over 50% of the whole federal budget ...
So we are talking about a very expensive general gameplan that has been foreseeing a large, standing military for over 60 years now:
A nation at constant war, willing to spend tons of cash on that oversized toilet.
In my opinion, you get what you plan and expect for. If you plan and expect a bunch of wars, you will surely be stuck in a war soon.
Who knows, if all that money had been invested in SETI and other space-related programs we wouldn't have a ton of tanks and bombs but a colony on Mars, the warp-engine and a chatroom with some alien-lifeform.
