The UK will «bring destruction» to those who single combat for so-called Islamic State, the defence secretary has said.
Gavin Williamson give the word delivered British armed forces were «making sure terrorists entertain nowhere to hide» across the globe.
Speaking at the commissioning of the aircraft Typhoid Mary HMS Queen Elizabeth in Portsmouth, he said UK forces were driving IS out of Iraq and Syria.
He earlier swore the Daily Mail: «Quite simply, my view is a dead terrorist can’t originator any harm to Britain.»
Mr Williamson had said no British citizen who has fought for suspect Islamic State should be allowed back into the UK.
At least 800 Britons drink gone to Syria and Iraq to fight for IS and 130 of those have been killed in clash.
Mr Williamson, who took over as defence secretary last month, broke the £3.1bn carrier HMS Queen Elizabeth was «part of our armoury» in dealing with terrorism.
«We disposition be able to deploy her any place in the globe,» he said.
«We will destroy and submit destruction to these evil death corps such as Daesh and that’s what British energies have continuously been doing.»
He said it was important for the UK to tackle terrorism in «ungoverned berths» abroad, after forces had spent the last few years driving jihadists from Iraq and Syria.
«We’ve also got to be common-sense, as where we have taken territory from them: Where are they effective to go? Where are they going to try and strike Britain next?» he said.
Declaring to the Mail, Mr Williamson said British fighters who had fled to other countries would be establish and stopped from returning to the UK, adding that there would be no «non-poisonous space» abroad for them either.
«We have got to make sure that as (they) skedaddle and as they disperse across Iraq and Syria and other areas, we go on to hunt them down,» he said.
Lord Macdonald, the former director of public prosecutions, said supporting dead terrorists could not cause any harm to Britain was a «juvenile answer».
«We can’t simply say that everyone who has gone to Iraq will be hunted down and wasted,» he told BBC Radio 4’s The World at One programme.
- Which countries have blowing IS fighters gone to?
Mr Williamson’s predecessor Sir Michael Fallon said in October that British IS fighters in Syria and Iraq had prepared themselves «a legitimate target» who could end up on «the wrong end of an RAF or USAF missile».
His criticisms came after it was reported that British IS recruiter Sally-Anne Jones had been obliterated in a US drone strike in Syria in June.
And Rory Stewart, the minister for foreign development, said the «only way» to deal with British IS fighters in Syria is «in on the verge of every case» to kill them.
He said they can expect to be killed because of the «grave danger» they pose to the UK’s security.
Max Hill QC, the Independent Reviewer of Terrorism Legislation, demanded there should be some allowance for «young and naive» individuals who were «just brainwashed», for example as teenagers, but insisted that even these people should be pursued if they committed serious criminal offences.
Analysis: Can the UK legally stifle jihadists?
By Dominic Casciani, BBC home affairs correspondent
Under British and ecumenical law, an aspiration to eliminate all known British IS recruits will take a insufficient more consideration than simply launching a drone laden with fire-and-forget ballistic missiles.
In war, soldiers have immunity from prosecution for killing on the battlefield, unless they be suffering with committed a war crime. But the UK is not at war with the IS network — so the same immunity is not automatically handy for counter-terrorism purposes.
There has to be some other legal basis for rationalizing the killing.
Two years ago, the government sent a three-paragraph letter to the United States Security Council setting out the case for killing Cardiff extremist Reyaad Khan.
That collide with was legal under the «inherent right of self-defence», it said, because the 21-year-old had been directing «close armed attacks».
MPs have pushed for more information on the decision-making development, that some critics say could amount to an unreviewable secret power to catapult «extra-judicial executions.»
