Common wisdom would purport that those on the so-called right    are and have always been hawkish and pro-war, while those on    the proverbial left have always been the tree-hugging,    peacenik, anti-war folks. For many conservatives,    unfortunately, this is more or less correct. However,    progressives have once again     airbrushed their own past, which is about as anti-war as,    well, war.  
    Much of this perception is relatively recent and primarily    boils down to the Iraq War. The neoconservative    warmongering was in full swing and for his part, Barack    Obama gave a rather     pleasant speech about his opposition to the war before it    began. In his book, Obama elaborated,  
      What I sensed, though, was that the threat Saddam posed was      not imminent, the Administrations rationales for war were      flimsy and ideologically driven, and the war in Afghanistan      was far from complete.[1]    
    Not terribly bad, at least for a politician.  
    Obama then proceeded to escalate the     war in Afghanistan, go to     war with Libya without Congressional approval, authorize    airstrikes in     Iraq as well as     drone strikes in Yemen, Somalia, and Pakistan while    saber-rattling at     Syria,     Iran and the     Ukraine. Even the American withdrawal from Iraq he oversaw    which is now being ballyhooed by clueless neoconservatives     was hardly different than the schedule     George W. Bush had already agreed to.  
    Indeed, as far as Democratic, and ostensibly progressive,    politicians were concerned, Obama was actually abnormal in his    tepid opposition to the Iraq War. Senate Democrats voted in    favor of letting George Bush go to war 25 to    20. Hillary Clinton, Joe Biden, Dianne Feinstein, and John    Kerry all voted yes.  
    Furthermore, it wasnt long ago that the supposedly    conservative Republicans were the ones against war and the    supposedly liberal Democrats in favor of it. The big difference    seemed to be nothing more than which partys politician was in    office. For example, regarding the military action in Kosovo in    1999, Senate Republicans opposed the resolution    giving Clinton authorization for military action 13 to 32 while    the Democrats supported it 38 to 3. The 2000    Republican Party platform even criticized the Democrats for    being too militaristic abroad. Only later, after almost    unanimous support on both sides of the aisle for the war in    Afghanistan, did the parties switch for Iraq. Well, sort of    switched.  
    Progressive opposition to the Iraq War has been very much    exaggerated. Both the left-liberal     New York Times and     Washington Post backed the war. Thomas    Friedman,     Christopher Hitchens, Jacob    Weisberg, George    Packer and     Jonathan Chait all supported the invasion. Current Senator    and liberal-favorite Al Franken    noted that  I believed Colin Powell. I believed the    presumption that the President is telling the truth. So I    thought, I guess we have to go to war. The popular liberal    blogger     Matt Yglesias explained his support for the war as having    been because he  adhered to the school of thought (popular at    the time) which held that one major problem in the world was    that the US government was unduly constrained in the use of    force abroad by domestic politics. In other words,    progressives werent getting as much war in the 90s as they    would have preferred.  
    Sure, most of them eventually repudiated their former support    (with the notable exception of Christopher Hitchens). But    almost everyone outside of a few neoconservative perma-hawks    have done the same. When Republican Congressman Dana    Rohrabacher was asked in 2010 how many of his Republican    colleagues thought the war was a mistake,     he responded, I will say that the decision to go in, in    retrospect, almost all of us think that was a horrible    mistake. Being against the Iraq War now is kind of like being    against slavery now. Its certainly the correct moral position,    but its not a particularly brave or impressive stance to take.  
    And while there were more on the Left who opposed the Iraq War    from the beginning, it must be noted that anti-war movement    amongst progressives quickly dissipated as soon as Barack Obama    was elected. And while some on the Left have opposed Obamas    many interventions (albeit quietly), youll find more support    than opposition amongst progressives for Obamas kinetic    military actions. For example, Nancy Pelosi     was pushing for a war with Syria while Progressive-favorite    Elizabeth Warren     wants to bomb Iraq. DNC Chair     Michael Czin even channeled his inner-neoconservative by    declaring that Rand Paul blames America for all the problems    in the world because of Pauls (unfortunately short-lived)    criticism of intervening in Iraq once again.
