I don't really know what threat you are talking about. Can you be more specific?
Sure, I can do that for you.
The first thing on the list of threats to millions of Americans is Trump's intention to make deep cuts to Medicare, Medicaid and Social Security. These are safety nets for people, they are what keeps people alive. Without them, people die by the thousands if not millions. He routinely uses an unsecured phone without any encryption protections. Do you think this is smart?
He has green-lighter a massive increase in the nuclear weapons and ballistic missiles arsenals of North Korea.
He has refused to try to arbitrate the on-going dispute between Japan and South Korea.
He has repudiated the JCPOA while Iran was fully compliant.
He has withdrawn from around 40 other pacts, agreements and treaties unilaterally and without good reason.
He has started trade wars —- which the US is losing —- with China, Canada, and Mexico and has attempted to start trade wars with the EU, Australia, and several other countries.
He had ended the SALT treaties that protected Europe from massive assaults with medium-range missiles.
He has ended the Open Skies treaty that allows mutual inspection between the US and Russia.
He betrayed the Kurds after they lost 11,000 killed and 32,000 wounded defeating ISIS (versus 89/450 US casualties.)
He betrayed the Ukraine and has attempted to make it a tool in US party politics.
He betrayed the Venezuelan opposition and firmly cemented Maduro in power as an ally of Russia.
He “de-normalized” relations with Cuba despite virtually unanimous support for normalization.
He has rolled back environmental and climate legislation and inserted “poison pills” into regulations to prevent them from being re-imposed by a future President.
He has literally surrounded himself with characters of ill repute and diminished honesty. He has forced the GOP to kneel to his will.
He has fueled racism and white nationalism in the US for his own political gains.
He has presided over the largest deficits in US history
*Possibly the most stunning thing Trump has done is to weaken the other two branches of government in order to become more powerful.
*Trump has shown himself to be more of a mob boss than a president for this country. He demands loyalty (or else) from his surrogates and he seeks revenge on enemies new and old. That's a mobster mentality, and should not be a personality trait of our president. If anyone disagrees with him, whether they're republican or democrat, he seeks to destroy them personally and professionally along with their entire family if possible.
*Trump has been endangering national security by gutting out the very agencies that the U.S. depends on to keep this country safe. He fires people who have experience and replace them with 'acting' loyalists who have no knowledge or experience of their jobs. Most of these 'acting' appointees are learning on the job.
*Trump doesn’t respect nor does he value our US allies and without having allies it’s much more difficult to gather intelligence which is vital to national security.
*He has done nothing to address climate change despite significant and growing environmental catastrophies in the US such as major forest fires, floods, hurricanes
*How many times has the Trump White House issued security clearances to people who didn't pass their background checks? They could be national security threats under the influence of foreign enemies to the US.
*Trump doesn't seem to understand that Kim Jong Un is a dictator who rules the most repressive regimes on the planet. Trump has come to his defense several times while refusing to stand with our allies to condemn his actions. Trump is easily corruptible and completely lacks an understanding of ethics
*He was responsible for abandoning our allies the Kurds in Syria which enabled thousands of ISIS prisoners to escape. He remarked that he didn't care because they 'would most likely harm Europe not us'.
*The primary threat Donald Trump is to America is that he held up his hand to swear an oath to uphold the office as the President of the United States and to the Constitution. Yet, he blatantly disregards Constitutional Law, even stating that he “can do anything I want”. His father Fred practiced extortion and don't believe for a minute that Donald didn't learn at the knee of his father. Who else could better pass sensitive information to and from Russia?
