Given that the UK's House of Commons rejected action against Syria's government in 2013, such a move may prove highly controversial.
The foreign secretary's comments followed remarks he made in a newspaper article in which he called opposition leader Jeremy Corbyn a "mutton-headed old mugwump".
Corbyn, the UK Labour Party's veteran anti-war leader, has suggested that he may halt UK airstrikes on the Islamic State group in Syria if he is elected prime minister on June 8.
This stance, coupled with his long standing support of nuclear disarmament, have been used as a point of attack by the ruling Conservative Party, who have branded Corbyn a 'security threat'.
"This is somebody who would certainly put the security of our country at risk. And if you want stronger and stable leadership then it has to be Theresa May and the Conservatives," Defence Secretary Michael Fallon said earlier this week.
According to the latest polls, the Conservatives look set to win a landslide victory with a lead of as many as 20 percentage points over the Labour Party, who have only just started to creep up in the polls.
