To the editor:

Threats to our national security will not be resolved by building a wall along our southern border, because that is not where the threat lies.

The real threat to our national security comes from a president who refuses to listen to his security advisors or anyone else, has caused the partial shutdown of the federal government because of his refusal to compromise, and who is ensuring that thousands of federal employees are now working without a paycheck.

Whether or not you voted for Trump, you must concede one thing: This man has proved to be a walking monument to ineptitude. That may work for him in his private life, but in the role as president, it is catastrophic to us as a nation.
