I like how you think about the future of the West and then at the same time want to weaken the West through Brexit.
So you believe if there was a war the UK would be weaker out of the EU. Seemed strong enough in 1939-1945, non EU countries like Aus, Canada, USA etc.
I think we would still have the backing of EU countries as well. So no weakening as far as i can see on that count.
