This bloke makes some good points
Jihadi brides such as
Shamima Begum could be just as dangerous as male foreign fighters if ever allowed back into the country, a former Scotland Yard counter-terrorism chief warned today.
Richard Walton, who led the Met’s counter-terrorism command for five years until 2016, said it would be a mistake to make
“simplistic” judgements based on the gender of a potential returnee in assessing the threat they pose.
He added that some British women who had travelled to Syria had played a “vital” role in plotting Islamic State attacks and that the radicalising effect that they might have on future generations of Britons should not be under-estimated.
“Women who joined Isis as ‘jihadi brides’, far from being passive actors or victims, are likely to have been participants in terrorist activities in Syria,” he said.
“Many will pose just as much of a security threat as their male counterparts.”
EDIT: this part underneath was something I wrote not Richard Walton just don't want people thinking im spreading fake news lol
A united front is needed and most likely new laws stating that if you go and join a terror organization you will face whatever the laws are of the land you go to and will receive no help or support from the government. Laws need to be in place to punish traitors to their country.
