How do changing regional alliances affect the conflict in Gaza?

When the cease-fire collapsed, the finger-pointing began.

Hamas blamed Israel for advancing on Rafah under the pretext of searching for tunnels.

Israel said it was trying to destroy a tunnel despite the cease-fire, and a suicide bomber emerged. Shots were fired, and an Israeli soldier was captured.

U.S. Secretary of State John Kerry blamed Hamas, calling it an outrageous violation of the cease-fire he had helped negotiate with U.N. Secretary-General Ban Ki-moon.

Friday’s broken cease-fire comes after an earlier Egyptian proposal was rejected by Hamas. In that proposal, almost all of Israel’s demands were met, but none of Hamas'.

That may signify a larger Middle East attitude shift after the Arab Spring.

Hamas is the Palestinian branch of the Muslim Brotherhood — the same group called a terrorist organization by Abdel Fattah El Sisi’s new government in Egypt.

Saudi Arabia and the United Arab Emirates don’t support the Muslim Brotherhood either, with Egyptian media reporting that Saudi King Abdullah bin Abdulaziz called Sisi the day of the first ceasefire proposal, praising it even though it sided more with Israel.

And while Syria and Iran have long been strong Hamas allies, both countries have cooled their support.

When Syria descended into civil war, Hamas sided with the rebels because they are both Sunni-led groups.

Syria’s President Bashar Al-Assad is from a branch of Shia Islam, as is Iran, the leading Shia power.

When Hamas sided with the anti-Assad rebels, Iran stopped giving Hamas more than $10 million each month.

Now Israel’s long-standing ally the United States is reaching out to new players to help mediate a deal: Qatar and Turkey. Both support Hamas.
