I disagree with you.  I believe our interests align with Mexico right now... it's just that Mexico was first on Trump's hit list (but don't be fooled into thinking Canada is not in for the same type of bully tactics to force us into some form of economic submission).  Canada is a trading nation, and does not have the population to support an isolationalist, inward-looking policy.  I believe we need to stand with Mexico, Germany or whoever else Trump tries to bully into submission.

Since you use an analogy from the 1930's, it's useful to note that those who tried to appease the bully from the 1930's ended up gaining nothing and losing much.  Perhaps let's think about the long-term consequences, before trying to run and hide from Trump's bully tactics.
