The Cabinet has decided to create physical obstructions, electronic devices, lighting systems as well as walls and fences to seal off the Turkish border and thus try to curb the uncontrolled inflow of people from Syria to Turkey.For the past few years, since the eruption of the Syrian civil war, there has been a steady flow of Syrians entering into Turkey who have been allegedly fleeing the conflict. Thus, Turkey is now hosting about two million migrants from Turkey who have spread all across the country.Turkey's open door policy for the Syrians was a humanitarian gesture by the Justice and Development Party (AK Party) government. At the time, Turkey did not turn its back on the Syrians fleeing for their lives and extended a helping hand to them - so much so that to date, Turkey has spent $6 billion of Turkish tax payers' money to host the migrants, which is unprecedented.However, the open door policy of Turkey has been seriously abused by some Syrians with ulterior motives. The two million that entered Turkey have not been properly screened and thus quite a few terrorists from various factions, agents of the Bashar Assad regime and some people who want to use Turkey as a stepping stone to get to Europe have exploited this weakness.So it is no surprise that some radicals of the Islamic State of Iraq and al-Sham (ISIS) may have slipped into Turkey. However, until recently, ISIS has used Turkey as a transit route to bring in and send out its militants from Syria to other parts of the world.The fact that an ISIS suicide bomber has launched an attack in the border township of Suruç killing 32 people and wounding about a hundred people has been an eye-opener for the government, and a warning that it is time to do something about the border.The government has now decided to seal off the border through various means and set up more stringent controls for those entering Turkey from Syria. This should have happened long ago, but as the saying goes "better late than never..."This also coincides with the high level meetings between Turkey and the U.S. to "deal" with ISIS. Ankara and Washington have agreed on a series of steps against ISIS and the cooperation has started with Turkey allowing the Americans to use İncirlik Air Base near Adana.What is interesting, meanwhile, is that ISIS radicals are targeting Turkey's Kurds and not Turkish interests. What is alarming is that ISIS and the Kurdish terrorist organization the PKK seem to be set to fight out their own war on Turkish territory in various forms and this should not be permitted. The ISIS elements inside Turkey that seem to be targeting the Kurds are not imported from Syria or Iraq but they are home-grown. Some people in Turkey seem to be tempted to turn a blind eye to ISIS and let them get at the Kurds. Thankfully, the government is not among them. This kind of logic of trying to use ISIS against the PKK may sound reasonable, but it is a mistake that should not be supported.Turkey has a duty to make its Kurds feel they are first-class citizens of the Turkish Republic. The Kurds on the other hand, have a duty to become part of the democratic political system and give up their armed struggle.
