Britain is prepared to "hit Houthi rebels in Yemen again" following the escalation of tensions in the region.
Grant Shapps insisted that the UK and US wanted last week's airstrikes to be a one-off but were prepared to take further action if deemed necessary.
He denied claims that the attacks were an escalation of conflict in Gaza.
He instead argued that it's an unconnected defence of global shipping and the right to navigate international waters.

The Defence Secretary added that it would have given the Houthis "too much information" if MPs had debated the strikes in advance.
He told Times Radio: "We had a very deliberate strategy of providing very clear notice to the Houthis and the Iranians that if they did not stop then there would be consequences.
"I can tell you, the Americans and myself, my opposite number over there, were very carefully coordinating our approach towards this to deliberately make it clear that they need to stop.
"They did not. And of course, you’ve seen the consequence."

Shapps added that while the strikes were intended to prevent the sort of "thuggish behaviour" attacking ships in the Red Sea, Britain would be prepared to strike again if the Houthis didn't stop.
He said: "We very much hope that they will take a lesson from this and stop harassing shipping which has a perfect right to be travelling through the Red Sea — these are international waters.
"Of course if the Houthis don’t stop we have to look at this again."
The Welwyn Hatfield MP denied Houthi claims that the attacks on the ships were in response to the Israeli attacks in Gaza.
He stated: "50 different nations have had their ships attacked, so it quite clearly isn’t actually connected."
Shapps claimed that the world was "more dangerous" than it had ever been, promising that defence spending would continue to increase.
Some 20,000 British military personnel are expected to be deployed across eastern Europe in coordinated exercises.
Prime Minister Rishi Sunak warned earlier today that the Government remains "prepared to back our words with actions", following joint UK and US air strikes on Houthi rebels.
