The talk about constitution, rule of law, etc doesn't matter ultimately. The constitution or the rule of law are just things we follow when it suits our interests. It's why we broke every treaty with native americans and committed heinous genocides against them. It's why we enslaved blacks and then treated them as second rate citizens after slavery. And how many illegal wars have we been engaged in?
All the intellectual niceties are meaningless. At the end of the day, nations act in the way that the elites ( or a sufficient number of the elites ) of the nation want them to act. Nations are created by the elites to benefit the elites.
