Answers will vary. Your answer might mention the War of 1812 and the pressures that drove US involvement in it as well as other military conflicts the nation has had with other nations. You might also note some of the differences between the United States during and after Washington's time. For example, expansion to the west increased the very dimensions of the nation and required many types of less-than-ideal interactions with Native Americans and immigrants from a variety of countries, which may have caused Americans to feel less humble than Washington about their place in the world. Also, changes in technology and telecommunications have put the United States in a very different position than when it was largely agricultural (versus industrial) and the means of communication today makes the world seem so much smaller. And finally, you might mention that President Washington was highly idealistic in his advice that the nation should not form parties, given that it did so with gusto after his presidency.
