As the White House is trying to sell its plan for military strikes on Syria to members of Congress, antiwar activist Darnell Stephen Summers says that constituencies will put pressure on their representatives to prevent another war in the Middle East.“If the idea is to portray a necessity for attacking Syria as a motive to protect Israel, there’s a big problem with that because as we have seen in the vote of parliament in Britain, people have definitely shown their displeasure with those plans,” Summers, activist with Vietnam Veterans Against The War told. “The same situation is in the United States where it’s becoming clear that the constituencies of these representatives, these people who are going to be up for election, they are not very happy with the prospect, with the specter of another war,” he added. A possible US attack on Syria “is going to cause untold suffering and untold heaths,” Summers noted. President Barack Obama has called for a military action against Syria while opinion polls show that the majority of Americans oppose any US military strike on Syria. A new Washington Post-ABC News poll showed that 6 in 10 Americans are opposed to missile strikes on the Syrian government over accusation that it used chemical weapons against militant groups. Obama on Tuesday called for a prompt vote from Congress authorizing the use of force in Syria. US Secretary of State John Kerry also said Tuesday it is time to "stand up and act" against the Syrian government. "This is not the time for armchair isolationism," Kerry said in his testimony before the Senate Foreign Relations Committee. In addition, House of Representatives Speaker John Boehner and Majority Leader Eric Cantor (R-Va.) supported Obama's plan for a military action, saying they will vote in support of the use of military force in Syria.
