"Gaza can send thousands of rockets targeting Iraeli citizens and they won't even say a word." -- I'm pretty sure the US is saying a word, and it is desire for a cease fire. Also, Hamas is dumb, but death count in the recent spate of attacks? Israelis: 1 died to a rocket, Palestinians: 1000 died in shelling. Looks like Israel is doing comparatively alright here. Why do you need the US doing more here? What is it you want them to do?
"Iran can make nuclear weapons and they won't even say a word." -- Clearly you are unaware of the current state of diplomacy on this issue. Last November an interim agreement was made, observers are checking to verify Iranian compliance in agreement for a lessening of economic sanctions. We'll see if a continuing agreement can be reached by next November. What would you have done differently? The fact that you claim that the US has not said a word makes me inclined to think you are not aware of reality enough to make a sensible suggestion, but you could surprise me.
"Russia can take over Crimea and they get bashed harshly with... a speech." -- The US can invade Iraq and Afghanistan and run military operations in Pakistan and get bashed mildly with... a speech. Iraq was a disaster perpetrated upon a bed of lies and incompetency. Would you consider it money well spent? Seriously? What is your proposed action on Russia and Crimea? You have complained about actions taken, without expressing what it is you actually want... and that's just not helpful at all. It sounds like you want more dick waving and war and are under the impression that it will help, but I could just be stereotyping you...
"ISIS can take over Iraq and kill thousands and they won't say a word." -- What do you want? Unending US military presence in Iraq? Who do you even want to be in charge of Iraq and why? What implications would your desires have?
Basically, it sounds like you want the US to prop up Israel, stop Iran by any means necessary, remove Russia from Crimea, and crush ISIS and prop up Iraq indefinitely. You want to do all of this heavy work and military mobilization (hint: that costs a ton of money [oh, and lives, especially if you count foreigners and care about that kinda thing]), yet simultaneously you complain about the government not cutting a dime of spending.
Your brain is broken.
