....make it harder for people where any terrorist atrocities have been committed to gain entry to the US....
Sounds good to me.
There's long been a 'watch list' of certain countries and the people from there got extra attention when they tried to get in the USA.
If say Germany has been inundated with people from those countries, Germany simply should get the same attention.
Agreed. Germany recently imported some 1.1 million people from Syria and Afghanistan. According to opinion polls, more than 20% of the population in these countries openly sympathize with the ISIS. That means at least 200,000 potential terrorists. Trump is absolutely correct. These people needs to be screened and vetted.
Have a link to those polls? And isn't it a jump to go from sympathize to potential terrorist? What was the reason given for sympathizing with isis? Wouldn't surprise me if some did to an extent in syria for example because of their fighting against assad. Or for perceiving them not to be as corrupt. Etc. Sympathizing is not the same as agree with and want to join isis. But I would go further than trump's plan. Build a big wall all around america. Don't let anyone in. The rest of the world won't let anyone out.
The problem with the wall is this.
First, not letting anyone in or out is unconstitutional regarding freedom. Second, it is against common law of the people in general... common law, the thing that is over and above the Constitution. Third, it will not work, because airplanes and missiles easily go over the wall, and tunneling can go under.
Bankers like the idea of the wall. Why? Because it will take a lot of work to build a big enough wall. Workers need to get paid. Payment comes to them through government borrowing the money to pay them. The bigger the wall the better... so that the banking Ponzi is strengthened by the creations of more new money in the form of loans to have the wall built.
Remember, the wall might be for you in some ways, but it is against you in more ways, especially as the bankers take up ownership of the planet through their Ponzi.
