The trouble is that Canada is too small to have anyone’s back, militarily or internationally, they can be a friend, and helpful, but they don’t register much on the list of countries that can have your back.
Britain still has some power and reach.
Canada is getting very rich. No news from there eh?
Canada’s Navy is bigger than the Royal Navy. And the British army now actually has more Generals than it does battle tanks.
Britain realistically has no more “reach”. Their forces are a shadow of 25 years ago. Realistically they couldnt do the Falklands again. The best they coud do would be to play defense. Their Offensive capability is gone. No Carriers, No Harriers, No Vulcan strategic bombers. Nothing bigger than a Typhoon. They couldn’t strike the mainland except with sublaunched cruise missiles.
They have obviously decided that they will only send a few units of infantry and Helos to anything we do and will never fight big war again. Sadly, they are probably correct as they are flooded over with Muslims.
