“Let’s see. Threats to attack England. Numerous attempts. All obviously done by the death cult. AND WHY THE HELL DON’T THEY EXPEL ALL THE MEMBERS OF THE DEATH CULT?”
Same reason we didn’t expel all the people of Irish descent when the IRA were setting off similar devices in London and other cities.
Threats here in the US would not cause the wimp a$$ed government to expel them either.
