Let's scrap Trident. It is pointless. And, given our financial worries because of Brexit, reduce our vast overseas aid budget for a time. Theresa May has ruled out both of these.
We face a huge nuclear threat. Obviously not from Russia - or even Iran - but from a nuclear terrorist attack. I don't see how Trident will help nor do I see that it is independent of the USA.
Putin is certainly bad news but he is not "the enemy". Muslim terrorism and extremism are. Migrants are the other great defence threat, effectively an invasion.
Three weeks ago the UK overcome the European threat to her independence. We made terms years ago, I regret to say, with the IRA. The final threat to the UK is the Scottish Nationalists. to combat that threat I like the very radical proposal of Lord Salisbury and others to make the UK into a decentralised federation. Rather like the plans of Gladstone, which an earlier Marquis of Salisbury opposed and which, had they been implemented, would have kept Southern Ireland in the UK.
I agreed with Theresa May that the UK should resile from the ECHR and was very sorry that she quietly dropped it after the referendum. The UK should also enter a reservation into our adherence to the UN Convention on Refugees, obliging us to accept European refugees. I believe that back in 1951 we did make such a reservation.
