Absolutely batshit.
Yes, let's hand partial control of foreign and defence policy over to Jen with her HND in Beauty Therapy, because I'm sure she's in a far better position to know what's best for the UK's security in both the immediacy and the longer term, than people paid to take advice from the international Intelligence community, the MOD, foreign allies etc etc
Almost as ridiculous is the "I don't want more UK kids dying in wars" nonsense. Cool, go and tell the world's demagogues we simply aren't playing any more. In fact, no need, because if you take this moronic attitude that foreign aggressors simply aren't the UK's problem and therefore we should just not get involved, their lackeys will be knocking down your front door before long and you'll be able to complain about it in person. Except you wont, at least, not if you want to stay out of some camp, workhouse, or want to avoid just being shot out of hand. Sometimes it's necessary to defend yourself, and refusing to do so on "moral grounds" just results in both you, the kids you are desperate to protect, and everyone else getting bent over and fucked in any case. Well done idiot.
Conflict doesn't go away just because you object to it on "moral grounds", and nor will the people determined to come and kick your teeth in for you.
