We should keep the Constitution because it gives the power to those that should have it. Federalists are the responsible ones when it comes to money and government. Anti federalists are jumping ahead of themselves. The Articles give them power, but they have no idea of how to run a government. They will destroy themselves.
With the situation going on in North Korea we should at least consider withdrawing from the Korean peninsula. We cannot really predict the outcome of interacting with North Korea, but we could influence it. The only problem is China, Japan, and Russia may not be willing to participate in Asian security.
