Security threat

As someone formerly enlisted in the Navy and an officer, I am concerned with the threat to national security posed by President Donald Trump. His attacks on our intelligence agencies and cozy relationship with Vladimir Putin are un-American.

Recently, Mr. Trump dismissed the input of his intelligence chiefs about the threats posed by Russia, China, North Korea, Iran and the Islamic State. Mr. Trump continues to question the assessment of our intelligence agencies that Russia meddled in the 2016 election. Mr. Trump is in an ongoing trade war with China that is adversely impacting the global and U.S. economies. He erroneously believes North Korea is not a nuclear threat to the U.S., and he is pulling our military out of Syria, which will allow ISIS to reconstitute itself and allow Turkey to attack our allies, the Kurds.

According to former Secretary of State Rex Tillerson, Mr. Trump doesn’t like to read. According to former Chief of Staff John Kelly, Mr. Trump engages in impulsive decision making. According to White House sources, it is difficult for Mr. Trump to comprehend and process complex information, such as intelligence reports and military scenarios. He does not concentrate on important matters. He is a threat to our national security and should be voted out of office. DONALD MOSKOWITZ
