Retired U.S. Air Force General Michael Hayden has likened the objective of military airstrikes in the Middle East to casual sex as it offers satisfaction but with little or no commitment.
According to the Washington Times, he arranged a conference call with reporters to warn about the dangers of relying on airstrikes.
Hayden said that the U.S. needs to be wary of strategies that put emphasis on airpower alone.
U.S. President Barack Obama said on Wednesday that they would not be sending troops into Iraq and Syria.
The Pentagon plans to train 5,000 Syrian rebels every year as a part of Obama's strategy to combat Islamic State militants.
