It has gotten to the point where illegal aliens are demanding a safer way to cross the border into the USA. See the Gateway Pundit for more on this.
The thinking behind Obama's non-intervention/permissiveness on immigration policy has nothing to do with America's security, but everything to do with his socialist aspirations of fundamentally changing America, and his legacy he leaves behind. Unfortunately, the legacy will be the mess he leaves behind and may prove catastrophic once he's out of office and safely tucked away somewhere.
Worse than his failure to secure our borders, Obama's administration has declassified Iran and Hezbollah as terrorist entities. He stated on VOX that climate change is a bigger threat than terrorism. Perhaps he needs to actually take a course in meteorology before making this claim, but I'll take a 0.02 F degree increase over the last decade than a beheading. And for anyone to say "the science is in," doesn't know anything about the scientific method.
But let's get back to terrorism.
Obama is working on declassifying the Muslim Brotherhood (MB) as a terrorist organization, which spits in the eyes of the FBI and UAE. It's likely that Obama needs to make this terror-funding group appear to be the good guys because he often meets with them in our White House. He also meets with the Council on American and Islamic Relations (CAIR) and the Muslim American Society (MAS). The names alone are oxymorons to what they actually wish to do to our country, which is, to destroy us from within.
Declassify terrorist organizations? It's hard to imagine how the definition of terrorism can be so flexible.
Obama is obviously more comfortable dealing with Iran and the MB than he is with our only true ally in the Middle East, Israel. We all know how much he and Netanyahu hate each other but is it also possible that Obama has caught the latest strain of the anti-Semite virus that has been plaguing the USA?
While CAIR makes crazy claims of Islamophobia, there is far more anti-Semitism being displayed all across America. But Islam likes to play the role of victim while simultaneously attacking you for victimizing them.
There are many people in the Middle East who believe Obama is taking sides in the sectarian fighting and is refusing to deal or discuss human rights violations that are taking place. He is turning a blind eye all for the sake of a nuclear deal with Iran and this will cause some of the middle class to turn to the Gulf states for help protect their towns, while the rural class joins the Islamic State or Al Nusra to protect their families.
So Obama will end his presidency with a legacy, but not the legacy he is hoping for.
