Exactly my point! Other "middle powers" as you label them are not nearly so fortunate in having neighbors who are as friendly and benign as the US, thus they are required to maintain respectable naval and military forces for national defense. Canada resides under the US nuclear shield and is also protected by our conventional forces, so is not required to, and does not maintain credible armed forces proportionate to the territory being protected. Now, you may not like that fact, but it's indisputable.

Your implication that the US maintains it's military in order to "bully others" as opposed to helping other countries is flat out insulting. If that was not your intention, say so.

And as Slipdigit has pointed out, you have made allegations about the condition and usefulness of the 50 US destroyers that were transferred to Britain in 1940. These allegations have been challenged and you still haven't provided any references to back up your remarks. At this point, I feel your credibility is seriously in question.
