Like you, I believe that if someone disowns the country where they grew up in, in favour of a country they are prepared to take up arms for, they should not be allowed back on any terms.
They should assume the citizenship of their chosen nation.....their passports revoked.
Though apparently this would render them 'stateless' and this is illegal......but they have chosen to be thus.....it wasn't ever something that the UK thrust upon them....it was something they chose to do...so I think the rules about statelessness need to be revised to cover such issues.
