Whoever was behind this attack, it has left many in Turkey worried that they are entering a new era in which political violence has become depressingly commonplace.
The outsize role of Kurdish fighters in the conflict and the potential that the U.S.-led coalition will arm and cooperate with them is one reason Turkey cites for refraining from joining the fray.
While the nation waits for President Barack Obama to announce his strategy for dealing with the threat posed by ISIS, U.S. officials have been traveling the globe, seeking out partners to help shoulder the burden.
The ceasefire negotiated last year between Turkey and the Kurdistan Workers Party, one of the government’s major accomplishments, is now in danger of collapsing as discontent grows over the lack of progress toward a lasting peace deal. This has serious implications for Turkish politics because the Kurds are an important voting bloc in Turkey that could help determine the winner of August’s presidential elections.
