From a comment to the Washington Post:

There is one effect of Trump’s destruction of the international order that hasn’t received enough notice—nuclear proliferation. Every country—even Canada—now has to think seriously about nuclear weapons for defense. Otherwise they are sitting ducks for conquest.

Any kind of nuclear non-proliferation agreement is out the window. This is terrible. It not only increases the risk of use by national actors, it greatly increases the risk of theft for terrorism.

In our greed for conquest we are inviting catastrophe.
