Harry was once a senior royal, but the line of succession has moved on and he has naturally lost his position. He is stubbornly chasing a relevance he no longer has. Having been the spare for so long he likely perceives his own family as the "spare family", ignoring the fact that the actual spare roles have moved on to the Wales kids, as is expected.
The irony is that if they had just stayed calm and kept things classy, they would probably be quite popular today.
This is the situation in a nutshell.
They are both so impulsive and won't take advice, either from the MiGS or from their own PR people, if the rapid staff turnover is anything to go by.. They're not interested in the long game - they try this, they try that, they try this again.
Yes - they had it to lose, and they lost it by behaving like a pair of sulky teenagers. If only they'd realise that the only chance they have to recoup some respect is to live quietly, shun publicity (but not make a massive fuss about shunning pubicity....😂) and work at some genuine, unshowy projects. But there's more chance of me flying to the moon. Harry in particular seems to think he can turn back the clock and that the UK will just forget all the trouble he caused.
