What exactly does it to mean to be 'antiwar'?

"What exactly does it to mean to be 'antiwar'? If liberals cluck in disgust at the label 'pro-life' — that it's a preposterous label because no one's 'anti-life' — then isn't 'antiwar' an equally meaningless label, since no one this side of Attila the Hun is uniformly 'pro-war'? If the media are to be consistent, shouldn't they call the people who favor war in certain circumstances to be 'pro-choice' on military action? There are many on the radical left who have made a career out of being against every American military action since the Spanish-American War. In public, they tell us that all war is bad, and that every outbreak of international violence is to be abhorred. But too often, in between the lines, many in the 'antiwar' crowd aren't opposed to war as much as they're opposed to America moving a military muscle. Some in the 'antiwar' movement actually aren't so opposed to military violence, even to include terrorism — if the enemy is America or her allies. During the Vietnam War, some peaceniks openly supported the communist Vietcong. During the Contra war, some peaceniks openly supported the communist Sandinistas. In the current war between Israel and Hezbollah terrorists, some have openly supported Hezbollah, as Hezbollah-flag-waving weekend rallies around the White House and in other cities recently illustrated. Calling them 'antiwar' then isn't as accurate in describing those radicals as the label 'anti-American'." - Brent Bozell
