Do the Democrat-Left ever get tired of repeating the OBVIOUSLY false Iranian, Chinese and Russian talking points, and siding against the United States, just because Trump or some other Republican is president? For 25 years now?

This has been called the most effective military attack in world history. The Ayatollah and his top 50 officials were all wiped out in the first 5 minutes of the war.
U.S. and Israeli strikes up to this point have bombed and destroyed 16,000 targets in Iran, including 80% to 90% of Iran's missiles, drones, naval vessels, and weapons/munitions factories.
Iran is rationing what they have left to fire, because they know there's no more coming after what they have now is used up.

What exactly is Trump "chickening out" from?
Iran has nothing left to fight with, and Trump's offer of a cease fire, that Trump knows Iran will break (that Iran is already breaking) just gives the U.S. military time to re-load and re-position for the next wave of U.S. and Israeli attacks, to finish the job. It is an offer by Trump to save what infrastructure he can in Iran, for the free and democratic regime that will replace the current dying Islamic regime.
There is nothing poorly-planned or "disgraceful" ( those are just Democrat / Iranian talking points narrative lies) .

Trump is not "guilty of war-crimes" (Trump has actually allowed less infrastructure to be destroyed in Iran than would have been destroyed in mos wars, bridges and electrical plants that Trump threatens to destroy if Iran does not negotiate, would normally have been destroyed the FIRST DAY in any other war between nations. So Trump is in control, and Trump is being very humanitarian and avoiding unnecessary civilian casualties and damage to Iran infrastructure.

And meanwhile Iran in January slaughtered a a minimum of 30,000 unarmed Iranian protesters, and slaughtered many other survivors in their hospital beds, and further slaughtered he doctors and nurses who treated their injuries, and even worse to female nurses who were raped by over 50 IRGC soldiers each, literally described as "raping their guts out". But NOT A WORD of criticism from Democrats about these ACTUAL war crimes and cruelty.
