America is the chief facilitator and benefactor of global capitalism. The military's job is to stabilize global markets on behalf of the transnationals that own government.
What do I mean by stabilize?
Walmart and Exxon make their money on products and labor that come from dangerous places. If these places become unstable - as they so often do - money is lost, economies are ruined. Put simply, America cannot afford for (say) the Straight of Hormuz to be shut down by terrorists. Therefore, we require a massive military umbrella - an empire of bases - to counter political instability.
AGAIN: Everything from Walmart to American clothing brands depend on ultra cheap resources & labor. Cheap labor increases the profits of shareholders, which is the point of capitalism. I'm talking about labor so cheap that it could only be maintained in places that lack human rights and essential human freedoms. How do you repress whole populations? How do you create the conditions for ultra cheap labor? You support a network of ruthless dictators, from Pinochet to the Shaw to Hussein and Gaddafi: all supported by the US Government until they became unmanageable. That's the problem with ruthless dictators. They're good at repressing their populations so US interests can usurp their resources, but those same useful dictators can sometimes go too far - Hussein and Gadaffi being the most recent examples).
Do talk radio republicans know how much money & weapons the US Government -- under both parties -- has given to Libya? Do they know how much support Reagan/HWB gave to Hussein in the 80s when he was gassing his own people? Do they know why Reagan and Bush 41 poured so much money and weapons into Iraq, or Iran? Do they know why Reagan removed Hussein's Iraq from the official list of terrorist nations? Do they know how deeply the American lifestyle is maintained by labor and resources that come from "bad" places, requiring arrangements with bad people? Do they understand that the American Dream is built from Chinese credit & terrorist crude? Do they understand that America's largest retailer could not function without the spectacular contribution of Chinese tyrants? Do they understand that talk of "freedom" and "free markets" is a sick joke?
Answer: no. Glen Beck and Rush Limbaugh never talk about how Washington manages the global system. They don't explain that because the oil comes from a bad place, sometimes we have to get in bed with bad people. They just speak in cliches about how "Freedom is on the march". They don't even know how much oil is produced in Libya, or the other vital resources we get from Northern Africa. This makes talk radio and FOX news a dangerous farce, because they are raising a generation of truly ignorant morons who simply don't understand how the capitalist engine gets fed.

The OP misses something fundamental. He thinks that the occupant of the White House has influence over the current system of military globalization - which is run on behalf of the corporate elite who fund elections and own both parties. Obama and Bush are mere reflexes.
Is Obama a hypocrite? Yes, by definition, because he is a politician. Democrats who oppose war are like Republicans who oppose spending: they are lying to get elected, so that they can get hold of the Big ATM and hand out money to the corporations who put them in office.
