I don't see how US authorities can be accused of disrespect for the "rule of law" if they try to keep bad policy from becoming law in the first place, especially if the law in question would conflict with the ultimate legal authority they have SWORN to uphold. As far as "contempt for the world community" I don't take it as a given that that's a bad thing. Some elements of the world community are without a doubt worthy of contempt.
"Some elements of the world community are without a doubt worthy of contempt."
I would go further and state the majority are without a doubt worthy of contempt. Most would like nothing better than to end the sovereignty of the United States and begin the income redistribution to the UN.
