He also still insists on sending terrorists back to their home countries, where they will regroup and hit us again.
No he doesn't. No one does. What he insist on doing is releasing the many people we rounded up on faulty suspicion of being terrorists who subsequent investigation found were not in fact terrorists, just falsely accused people. Of the 700+ Guantanamo detainees, more than 2/3rd were found not guilty and released before Obama took office. He wants to put those who have not been cleared or have been found to be terrorists in supermaximum security prison from which no one has ever escaped, as we've always done with terrorists.
Though in fact, he has been completely dragging his feet in releasing even the people we already know to be innocent, who have been completely cleared and had to suffer in an extralegal gulag for years. There are many innocent people left still suffering this fate either because Obama doesn't truly believe in the rule of law or because of the political ramifications that will come from your ilk who believe any Middle Easterner ever accused of a crime must be guilty and must be punished, facts be damned.
The Constitution requires anyone the U.S. holds have access to a trial, to deny them one or hold them even in the event of a judicial ruling that they are not guilty is not only illegal, not only immoral, but further adds to the perception of the U.S. as a hypocritical country that does not honor its values and helps recruit ever more people to join the ranks against us.
It is abandoning our core principles out of an overwhelming, trembling fear of terrorism that not only destroys America internally, but ever increases the external threat.
