This may be drifting a bit off thread, however, I'll continue.
1. Yes Trump wants to deal with individual countries so that the ultra powerful US economy can pick them off, one by one. A block of 27 is more difficult for them.
2. Agreed that Russia wants to weaken the EU and also cause difficulties for NATO, whom he feels seriously threatened by.
3. Why should the EU want the UK to fail after leaving ?, surely they want to continue trading,even though they would be dearer following the crash of the £.
4. Which is precisely the reason that the Trump corporation wants the UK out.
UK crashes out no-deal. £ crashes to perhaps equity with the $. US big corp moves in, buys up what is left of UK business and institutions at bargain price. Asset strips an leaves UK as a vassal state, a colony with similar status to Costa Rica.
How would you like that? Before you scoff, remember how big corp US aided the smash and grab of former USSR assets in the post Gorbachoff (Yeltsin) era. The origin of the pro western Russian billionaire oligarchs. This may be developing into a blog but I can't understand why so many Brits are so blinded by the bright lights of the USA that they cant see the crass objectives of that administration.
