If someone said the two major political parties in America are largely beholden to corporate and plutocratic donations/interests, and that it threatens our democratic principles, I would whole heartedly agree.
If someone said there is no difference between the GOP and Democratic Party; then I would have to submit the hundreds of thousands of dead/wounded civilians and soldiers due to GWB administration's illegal invasion of Iraq as evidence to the contrary.
Even in this last election, the GOP demonstrated that they had learned nothing from Iraq. The Republican presidential candidate had a hard-on to attack Iran, imploring voters to support yet another costly international conflict.
In contrast to the GOP's predictable MIC profiteering and warmongering approach:
President Barack Hussein Obama's Democratic administration is currently holding talks with the Iranians to peacefully resolve our differences.
