On Saturday evening, a car bomb and a suicide bomber shook Istanbul's European shore. When today's paper went to the press, the death toll stood at 38 – 30 police officers and eight civilians. According to the Interior Ministry, the initial findings suggest that the deadly attack was perpetrated by the PKK, an armed group that Turkey, the U.S. and the European Union recognize as a terrorist organization.The news of a powerful explosion in Istanbul was followed by a series of statements all too familiar. An investigation was launched into the assault. The White House and the European Union issued statements to condemn the attack and offer their condolences to the Turkish people. Others followed suit.Needless to say, everybody in Turkey appreciated the irony of state sponsors of terrorism mourning the loss of innocent people killed by their bloodthirsty lap dogs. The blood is on your hands. Your taxpayer dollars are at work. Take pride in your achievements!In the name of fighting Daesh without placing American lives at risk, U.S. President Barack Obama outsourced the counterterrorism effort to the People's Protection Units (YPG), the PKK's Syrian franchise. Before long, Washington's weapons were directed at the citizens of Turkey, a fellow NATO ally. You kept silent when militants trained in northern Syria perpetrated attacks on Turkish soil. You looked the other way even though the PKK detonated car bombs at the heart of our nation's capital. Today, the best policy would be to spare us your empty words.The ladies and gentlemen in Europe stand accused as well. For years, the PKK was able to operate freely across the European Union on the one condition that they would spill blood elsewhere and not target EU citizens. In recent years, we have seen an uptick in recruitment and fundraising efforts as Europe's silent consent effectively turned into active cooperation with terrorists. When we turned to Brussels and Strasbourg for support, it became clear that our supposed allies had sided with an armed group, which they themselves called a terrorist organization, against a candidate country. When we called out Europeans leaders on their support for terrorism, they started throwing punches: First, they protested the arrests of people with PKK ties and called it a crackdown on dissent. Then they asked Turkey to soften its stance on terrorism and adopt a weaker anti-terror legislation. Finally, the European Parliament called for the suspension of membership negotiations with Turkey citing the state of emergency.Western media soon joined the chorus. Hailing bloody terrorists as peace-loving freedom fighters, they turned into PKK mouthpieces and collaborators. Just three days before Saturday's attacks, The New York Times shamelessly sought to whitewash the group by arguing that "the PKK may be a terrorist organization in the view of the Turkish government, Europe and the United States, but it has also long made women's rights a centerpiece of its political platform."But enough is enough. The most recent terror attacks in Istanbul must mark a turning point in Turkey's counterterrorism campaign. To prevent future attacks against our citizens, we have no choice but to launch an all-out effort to defeat the terrorists for good. After all, there can be no freedom to engage in acts of terrorism – not in our house anyway.Moving forward, all individuals with ties to the terrorist group – whether they are politicians, lawyers, journalists or foreign nationals – must be tracked down, caught and brought to justice for helping armed radicals hurt innocent people.Across the Syrian border, we must find and destroy terrorist targets where future attacks are being planned today. Having removed Daesh from our borders, we cannot tolerate the presence of another terrorist group, the YPG, in places like Afrin, Manbij and Kobani. As such, the Turkish military must be immediately dispatched to northern Syria with a mission to eliminate all terrorist threats and remain in the area until the situation de-escalates.Turkey faces an existential threat. There can be no middle way in the fight against terrorism. Those responsible for killing 38 Turkish citizens and their sponsors must pay the price for their actions.
