According to a Gallup poll conducted on May 28-29, 68 percent of the US citizens are against any US military involvement in Syria even if diplomatic and economic efforts fail to resolve the 2-year old conflict.

More Republicans (31%) than Democrats (20%) are likely to support a possible US military action in Syria, the poll showed.

The poll also found that the number of college graduates in favor of military action in Syria is less than those without a college degree.

Other polls conducted by Fox News, CBS, and Reuters also indicate that the majority of Americans are against US military involvement in Syria.

Despite opposition from their publics, the US and its allies have been pushing for military intervention in Syria.

US President Barack Obama has said that the United States was "looking at all options" in Syria.

Late in April, a group of Republican lawmakers urged Obama to intervene militarily in Syria to “resolve” the crisis.

On May 28, Hawkish Senator John McCain visited the country and held talks with terrorists fighting against the Syrian government. His visit came amid US efforts to beef up military aid to rebel forces in the country.

The Obama administration has also been considering the possibility of setting up a no-fly zone over Syria and asked the Pentagon to draw plans for doing so, according to The Daily Beast.

Damascus has repeatedly said that the crisis, which started in March 2011, is being engineered from outside the country. On May 18, Syrian President Bashar al-Assad said mercenaries from 29 different countries were fighting against his government in different parts of the country.
