The correct answer to this open question is the following.
The concerns that George Washington had about the nation's foreign affairs are not applicable today because we are living in a globalized world in which nations are connected like never before, and all modern and democratic countries need each other in order to grow and prosper.
George Washington -the first President of the United States- had a peculiar way of thinking regarding foreign affairs during his tenure as president. He did not like the idea to have permanent agreements with foreign nations. He preferred short agreements in case of wars or conflicts, and as soon as the conflict was over, the agreement too.
But that was then, and today is different. Every single country in the world needs the help of other countries. That is why nations sign cooperation treaties in trade, foreign policy, and more.
