SYRIA

A U.S. warplane shot down an Iranian-made armed drone after it approached U.S.-led coalition soldiers in southern Syria yesterday, the third occasion in two weeks on which the U.S. has brought down a pro-Assad regime aircraft seen as a threat to coalition and rebel fighters, Dion Nissenbaum, Ben Kesling and Maria Abi-Habib report at the Wall Street Journal.

The downing of the drone merely “helps those terrorists whom the United States fights,” the Russian deputy foreign minister said yesterday, though behind the heated remarks there were signs that the U.S. and Russian militaries were working together to manage the situation, writes Michael R. Gordon at the New York Times.

Russia has requested a “detailed explanation” of why the U.S. shot down a Syrian warplane Monday, Russian Foreign Minister Sergei Lavrov said last night, the AP reporting.

The race to capture territory vacated by the Islamic State in eastern Syria is raising the risk of confrontation between the U.S., Iran and Russia, a risk that is already materialising, Rebecca Collard, Erika Solomon, Najmeh Bozorgmehr and Katrina Manson examining the signs at the Financial Times.

The ongoing surge of U.S. military operations and arms sales across the Middle East by President Trump is happening without an engaged public discussion about the risks or about diplomacy or other tools needed to protect the U.S., the downing of a Syrian warplane on Sunday and last month’s strike against a pro-Assad regime militia just the latest episodes in an escalation that lacks well-defined goals and strategy understood by the American public, write former Hillary Clinton campaign chair John Podesta and Brian Katulis at the Washington Post.

The KOREAN PENINSULA

China has failed to convince North Korea to halt its nuclear and missile programs, President Trump declared via Twitter yesterday – an “extraordinarily cavalier” statement given his formerly ardent efforts to obtain the cooperation of Beijing in dealing with Pyongyang, observe Mark Landler and Gardiner Harris at the New York Times.

South Korean President Moon Jae-in is willing to collaborate with the U.S. in putting maximum pressure on North Korea to give up its nuclear program, but believes it is also important to send a message to Pyongyang that “if it decides to denuclearize and to come to the negotiating table, then we are willing to assist them,” he told the Washington Post’s Lally Weymouth ahead of his first visit to the White House next week.

Discussions on taking on a potential role as broker for negotiations with North Korea are being discussed by the European Union with South Korea and China, E.U. officials said, Jeremy Page and Laurence Norman reporting at the Wall Street Journal.

Japan will test its missile interceptor capability tomorrow in the wake of several recent missile tests by North Korea, according to Japanese media, Ellen Mitchell reporting at the Hill.

Is war with North Korea the next step? President Trump has begun the U.S.’ final campaign to disarm North Korea, but will it involve going after Chinese banks, or war with Kim Jong-un? Gordon G. Chang writes at The Daily Beast.

TRUMP-RUSSIA INVESTIGATION

Former national security adviser Michael Flynn was present while C.I.A. Director Mike Pompeo briefed President Trump on sensitive intelligence nearly every day for three weeks in January despite senior officials across the government being convinced that he had become vulnerable to Russian blackmail, Matt Apuzzo, Matthew Rosenberg and Adam Goldman writes at the New York Times.

“To my current knowledge, the Russian government did not through any cyber intrusion alter ballots” in last year’s presidential election, former Homeland Security Secretary Jeh Johnson intends to say in his prepared statement before the House Intelligence Committee today, the Hill’s Joe Uchill reports.

President Trump’s unpredictable actions are to blame for slowing down the Senate Intelligence Committee’s investigation into possible Trump-Russia collusion, the vice chairman of the committee Sen. Mark Warner (D-Va.) said yesterday, referring to the firing of former F.B.I. director James Comey and the spreading of rumors that Trump might fire special counsel Robert Mueller. Max Greenwood reports at the Hill.

Attorney General Jeff Sessions has retained the services of a Washington lawyer – Charles J. Cooper – who was sitting behind him as Sessions testified before the Senate Intelligence Committee as part of its Trump-Russia investigation last week, Sari Horwitz reports at the Washington Post.

GULF-ARAB DISPUTE

“We are mystified that the Gulf states have not released to the public nor to Qatar the details about the claims they are making toward Qatar.” State Department spokesperson Heather Nauert released a “blistering critique” of Saudi Arabia and its allies enforcing a two-week embargo against Qatar yesterday in a statement that seems to put Secretary of State Rex Tillerson further at odds with President Trump over who is to blame for the dispute, writes Gardiner Harris at the New York Times.

Saudi Arabia’s King Salman’s decision to elevate his son Prince Mohammed bin Salman to become crown prince in place of his nephew Mohammed bin Nayef today comes at a time when the Kindom is heading a bloc of Arab nations that has launched a campaign to isolate Qatar and almost certainly means the continuation of a more assertive Saudi foreign policy and a strong alliance with the U.A.E. in pursuing those policies, write Sudarsan Raghavan and Kareem Fahim at the Washington Post.
