Iran is anxious to avoid a war with the US

For all its bravado and outrageous aggression through its multiple proxy forces it likes to call the Axis of Resistance, Iran is in no position to fight a full war with the United States and knows it. This is why Tehran has been desperately pleading it had nothing to do with the drone strike on the US outpost in Jordan which killed three soldiers and injured more than 30 others. Whether the denial is true or just a plain lie, it shows the ayatollahs want to muddy the waters for Joe Biden, to make him decide aganst attacking Islamic Revolutionary Guard Corps targets in Iran just in case they weren't behind the deaths. Basically, whether Iran actually plotted to kill American soldiers or not, their fingerprints are all over the drone attack. They provide the weapons for all these Islamic militia groups and are probably supplying the intelligence to make sure their proxy forces know what to hit. There's an Iranian warship in the Red Sea which has intelligence equipment on board. So Biden would be in his rights to conclude that Iran was to blame for the deaths of the three Americans and should be punished. But I seriously doubt he will authorise the launching of 100 Tomahawk cruise missiles at IRGC facilities in Iran, as someone in US Congress has been recommending. This is Joe Biden, not Donald Trump, although it is election year and the president will not want to be accused of being soft on Iran!
