Letter in response to “Minnesota should aid in refugee crisis”

Opening doors for the Syrian and Iraqi asylum-seekers comes with the risk of transporting Islamic State fighters to the heart of Europe and to the United States.
Indeed, situational heartbreaks, like that of Aylan Kurdi, the drowned 3-year-old Syrian boy, give the Islamic State the opportunity to penetrate from behind societal lines and to recruit or attack the West from the rear. While it shoulders on humans to save other humans, caution is required not to transport an enemy.
Who knows the background of each of these hundreds of thousands of refugees flooding to Europe? The U.S. intelligence is unable to tell who’s who! So are European intelligence organizations. Refugees’ sectarian culture tends to hide the bad guys. 
Sending highly trained operatives to the U.S. and Europe is what jihadists have long wanted. This massive migration influx presents just that opportunity, and they will use it wisely. 
True, America’s life-saving missions across the globe have been noble, and the current migration emergency is a test for the U.S. Therefore, as the editorial emphasized, “the U.S. has a moral responsibility to allow refugees a safe haven.”
To summarize, the U.S. promising to accept as many as 10,000 refugees in the coming year is a good move toward sustaining American diplomatic symbols abroad. It could also mean admitting more Islamic State fighters and extremist jihadists into states like Minnesota, where terrorists and their sympathizers meet.
According to WND, an independent news website, there are “4,000 fighters ‘ready’ throughout the European Union.” It also says these “covert terrorists” are “awaiting orders.” 
If more unfiltered migrants make their way to the West, there is going to be a catastrophe for some and a complete success for others. If we have to transport the unknown, diligence is highly recommended.
