Yes, we are back to square one.

"Unfortunately we continue to see signs that the Assad regime may be renewing its use of chemical weapons including an alleged chlorine attack in northwest Syria on the morning of May 19," State Department spokesperson Morgan Ortagus said in a statement.
"We are still gathering information on this incident but we repeat our warning that if the Assad regime uses chemical weapons, the United States and our allies will respond quickly and appropriately," she added.

No proof yet, but then a lack of evidence has never prevented us from bombing someone.
Meanwhile, the Syrian government is under assault by terrorists.

Rebels in northwestern Syria launched a counterattack on Tuesday against pro-government positions and fighting killed more than three dozen combatants from both sides, a war monitor said...
The territory is largely controlled by Hay'et Tahrir al-Sham (HTS), an armed group that formerly represented al-Qaeda's Syrian wing. The Syrian government has vowed to remove HTS from the region.

So Assad is literally under siege by the same group that attacked us on 9/11, and we are threatening Assad for fighting back. Just imagine if the news actually reported it like I just said it.
Meanwhile, the Dems are pressuring Trump to start a regime-change war.

Hundreds of US lawmakers signed a letter to Donald Trump on Monday calling on the president to exercise “clear and sustained American action” in Syria to eliminate jihadist threats and to protect Washington’s allies.

The letter, signed by nearly 400 lawmakers from across the Senate and the House of Representatives, urges Trump to send “a message of resolve to malign actors in the region” – including Iran and Russia...
Signatories also called on Trump to “increase pressure on Iran and Russia with respect to activities in Syria,” accusing both countries of attempting to change the trajectory of the war “at the expense of Syria’s people.”

First of all, unless we start bombing Syria "the trajectory of the war" is that it's almost over.
Secondly, Syria's refugees are returning to Syria as Assad recaptures the country from the jihadists that we armed.

Laughably, Congress is moving to contain Trump's war-making powers at the very same time it wants him to start a war.

The House Appropriations Committee voted to advance an amendment to a defense spending package on Tuesday that would sunset the 2001 Authorization for Use of Military Force (AUMF) issued after the 9/11 attacks. The bipartisan legislation would provide Congress with new tools for containing the Trump administration as it meddles in foreign conflicts and stokes military tensions with Iran...
On Friday, 100 House Democrats urged Trump in a letter to “resist factions” in his administration that are “leading our country down a disastrous path to war” and warned that the White House cannot declare war with Iran without approval from Congress, including under the 2001 AUMF. Administration officials are reportedly building a case to declare Iran a terrorist threat in order to circumvent Congress and launch military strikes under AUMF authority if the administration decides to engage Tehran.
