Turkey and US recently agreed to cooperate in the fight against IS.
Turkey has managed to bomb 100 PKK Kurdish camps in Iraq in the last few days. Even the syrian Kurds (YPG) have reported of being attacked by the Turkish military. IS now has its own air support, says the Kurds.
A weakened PKK means a weakened Kurdish resistance against IS. The Kurds have helped US with Saddam & Bin Laden. The Kurds are protecting Christians with Soviet-weapons from the 70s against IS!
Brave and honorable American soldiers have joined the fight against IS by fighting alongside the Kurds. President Obama has in effect given Turkey the green light to bomb Americans as they please!
