we cant afford defence so scrap the lot of it

Which is of course the biggest fallacy going. We could afford a much larger military but we choose as a country to spend our revenue elsewhere.

I think most of those types are Guardianistas still not over post imperial guilt 30 years after most of the country have moved on!

The truth of the matter is that, if we behave like this, the global community sees the UK as a nation unwilling to meet its commitments, acting in bad faith towards its friends and allies and cutting off those who depend on it for their safety. Would you do business with a person who you saw as willing to back out on their friends and partners and willfully leave people in the lurch?. Personally I wouldn’t.

Not only that, there will be plenty of countries worldwide willing to step into our place to take over those responsibilities.
