Is Sunak actually proposing conscripting Irish Nationalist and Republican teenagers in the North of Ireland to the British Army? If so, lol, good luck with that.
If not, I’d just point out that the North of Ireland was
exempted from conscription in both WW1 and WW2. If it is to be exempted from National Service, maybe a lot of teenagers would find changing their home addresses to Belfast or Derry an attractive option?
