At yesterday's Oval Office press conference with French President Emmanuel Macron, President Trump said of Syria, "We'll be coming home, but we want to leave a strong and lasting footprint."

Yet it's doubtful the U.S. could maintain a strong or lasting footprint without committing to stabilization, which would involve a larger U.S. troop presence or support for a Turkish security zone in northern Syria.

The big picture: Little has changed since the coalition airstrikes on April 13, a response to President Bashar al-Assad's latest chemical weapons attack, and the White House continues to send mixed messages about the U.S. presence in Syria.

Regional allies are unsure of U.S. commitment, leading them to make choices that at times exacerbate the conflict. Two weeks ago, for example, Israel launched an airstrike on a Syrian airbase in response to the chemical attacks, killing 14 people, 7 of whom were Iranian. And Turkey, a NATO ally, has also caused tensions to flare by acting unilaterally in northern Syria.

Meanwhile, U.S. enemies have exploited the U.S.' strategic negligence, complicating the White House's options as Iran extends its influence to the Mediterranean and Russia establishes itself as the region's powerbroker.

The bottom line: So long as the U.S. and its Western allies continue to avoid assuming a more substantial leadership role in the region, Syria will remain mired in crisis and confusion.

Trump and Biden clash over COVID: "It is what it is because you are who you are"

Joe Biden attacked President Trump at the presidential debate on Tuesday for his response to the coronavirus pandemic, accusing him of panicking and failing to prepare for the crisis when he was warned about it in February.

The big picture: "It is what it is because you are who you are," Biden said, alluding to an answer Trump gave in an interview with "Axios on HBO" when asked about the 150,000+ death toll from the coronavirus. Trump responded by claiming that Biden would not have shut down travel from China in the early days of the pandemic, and he defended his administration's mass production of ventilators and protective equipment.

Biden: "I am the Democratic Party right now"

Responding to President Trump's insistence that the Democratic Party "wants to go socialist medicine," Joe Biden said at the presidential debate on Tuesday: "I am the Democratic Party."

Why it matters: Trump has repeatedly claimed that the Democratic nominee is not in control of his party and that he will be "dominated" by progressives like Sen. Bernie Sanders and Rep. Alexandria Ocasio-Cortez. Unlike other candidates who Biden ran against in the Democratic primary, he does not support Medicare for All or abolishing private health insurance.
