IMHO Muslim immigration is not a terrorism issue. Its a social-engineering issue. The Left needs them to dilute US culture and standards, and provide another ethnic-religious-political wedge. They do not fear terrorism - because they can control it
The deep-state IC can, easily, track Muslim radicals in the USA. Muslim radicals usually have networks and connections that clearly lead back to powerful people in places like Saudi Arabia. Thus, they are controlled, state actors in many ways.
If Muslim terror occurs in the USA, I am convinced it occurs because it is allowed to occur, for political reasons.
How did Trump, who was supposedly so hated by Muslims, avoid a single domestic jihad incident, while Obama, who aligned with CAIR and was promoting them always, had so many attacks from Boston Marathon to fort Hood to San Bernardino and Orlando?
agree with most of your points, thanks
(but immigration from terrorist Muslim countries is definitely a defense, security, safety issue! there have been Thousands Muslim terrorist attacks, bombings, and stabbings (and arsons) around the world including a number already in USA and so many in European countries they can’t keep up with the counts).
But yes on all of your points, too. thanks
