The head of the UK foreign policy justified Monday the last week's missile launches, adding though that the attacks weren't aimed at removing Syrian President Bashar al-Assad.
"There's one overwhelming reason why this was the right thing to do and that is to deter the use of chemical weapons, not just by the Assad regime but around the world," Johnson said.
Last Saturday, the United States, France, and the United Kingdom launched strikes on a number of targets in Syria in response to an alleged chemical attack in the Damascus suburb of Douma.
According to the Russian Defense Ministry, the three countries fired over 100 cruise and air-to-surface missiles, most of which were shot down by Syrian air defenses.
Following the accusations, the Syrian government has strongly denied being behind the alleged attack and stated that the missile strike was "brutal aggression."
