With Moscow threatening sanctions against Turkey in the aftermath of the downing of a Russian warplane on the Syrian border, plans for a Russo-Turkish free trade zone appear be on hold—along with key energy projects. Foremost among these is the TurkStream gas pipeline, which Economy Minister Alexei Ulyukayev said Moscow could "restrict." (Reuters) TurkStream is being developed by GazProm, the Russian energy giant, to export Russian (and potentially Central Asian) natural gas through Turkey via the Black Sea. Ulyukayev's hedging is understandable: this has long been a strategic project for Moscow, which has long nurtured a grudge over the Baku-Ceyhan pipeline—linking the Caucasus to Turkish port of Ceyhan through a route that by-passes Russia.

The situation on Turkey's Syrian border has only escalated since Turkish forces shot down a Russian warplane two days ago. A Russian rescue helicopter was shot down by Syrian rebels while searching for the two pilots of the downed warplane. The helicopter was forced to make an emergency landing in a regime-held area of Syria's Latakia governorate. The rebels were using (possibly CIA-supplied) US-made TOW missiles. (The Mirror) One pilot was rescued in the joint Russian-Syrian operation and brought to a base in Latakia, Moscow says. A Russian marine was also reported killed during the rescue mission. The other pilot was shot by rebels as he parachuted from the hit plane, according to Moscow. (AP)

Turkey shot down a Russian warplane on the Syrian border Nov. 24, aparenently after it violated Turkish airspace. Vladimir Putin said the Su-24 was hit by air-to-air missiles fired by Turkish F-16s while it was flying over Syrian territory. A military statement from Ankara said the plane violated Turkish airspace in Hatay province and was warned "10 times in five minutes." Reports indicate the plane crashed in Syrian territory, near Yamadi village of Latakia governorate. (Al Jazeera, BBC News) The two pilots reportedly survived the crash but were captured and summarily executed by members of a Turkmen rebel militia. (Reuters) There is some ambiguity about what actually constitutes the border in this area, as Turkey has established a military-controlled buffer zone in Latakia.

The United Nations Security Council on Nov. 20 unanimously adopted a new resolution (PDF) calling on all member states to fight to eradicate ISIS. Introduced by France in the wake of the Paris attacks that claimed 129 lives, the resolution asks states to do what they can to destroy ISIS safe havens in Syria and Iraq. Characterizing ISIS as "a global and unprecedented threat to international peace and security," the Security Council warned that further attacks are expected, given recent ISIS attacks in Tunisia, Turkey, over Egypt with the downing of a Russian plane, and in Beirut and Paris. By a 15-0 vote in favor, the Security Council pledged to attack all terror organizations in the Iraq and Syria region, including Nusrah Front, both with physical force and by working to crack down on foreign fighters joining the cause and by blocking financing.

In the wake of the Paris attacks, the centripetal tendency in world affairs seems to hold sway—a further Great Power convergence against ISIS. When the French nuclear aircraft carrier Charles de Gaulle reaches its position off Syria's coast, it joins a Russian guided missile cruiser already there—and cooperation between the two powers appears imminent. "Under the Russian president's decree, the General Staff is working out joint anti-terrorism operations with the French Navy," said Col-Gen. Andrey Kartapolov, deputy chief of staff, according to Moscow's state news agency Tass. "With the arrival of the Charles de Gaulle warship to the Syrian shore we will organize joint military operations." Citing Kartapolov, Tass also claimed, "Russian warplanes have destroyed about 500 fuel tank trucks that were illegally transporting oil from Syria to Iraq for refining." While not stated, this presumably means ISIS oil. (NPR)

NATO is just winding up its biggest military exercise since the end of the Cold War—Operation Trident Juncture, involving 36,000 troops and more than 140 aircraft and 60 ships from over 30 countries over a month-long span. The maneuvers were centered around Sardinia, where hundreds of local residents attempted to block the troops and craft in a civil disobedience action. They were angered by rising cancers, leukemia and birth defect rates on the island, where the soil and groundwater are contaminated with heavy metals, jet fuel and depleted uranium from decades of military operations and weapons testing there. Maneuvers were also held in Spain, Portugal, Norway and the Atlantic. (Gizmodo, Nov. 10; Revolution News, Nov. 3; ANSA, Oct. 21; NATO, July 15)

Here we go. Another step towards open US embrace of genocidal war criminal Bashar Assad and his regional sponsors. AP reports today that Iran has been invited to participate the next round of Syria peace talks set to open this week in Vienna, with Secretary of State John Kerry, Russian Foreign Minister Sergey Lavrov and several top European and Arab diplomats in attendance. State Department spokesman John Kirby said "we anticipate that Iran will be invited to attend this upcoming meeting." While paying brief lip service to supposed White House disapproval of Iran's "destabilizing activities" in Syria, Kirby said US officials "always have recognized that at some point in the discussion, moving toward a political transition, we have to have a conversation and a dialogue with Iran."

There was brief media splash last month after Germany's ZDF TV reported that the US is planning to replace 20 nuclear bombs deployed at Büchel airbase. According to the reports, the current B61 bombs are to be replaced this year with B61-12s, a newer version that is said more accurate and less destructive (potentially making their use more "thinkable"). Alarmingly, reports indicated that the new variants can also be fired as missiles, while B61s had to be dropped from aircraft. Moscow of course immediately responded by threatening "countermeasures"—including deployment of Iskander ballistic missiles to Russia's Baltic Sea enclave of Kaliningrad.
