MOSCOW, April 27. /TASS/. A state of "no peace, no war" that followed the 40-day war the United States and Israel waged against Iran cannot last long and another spiral of escalation may be much more brutal and wider, a Russian expert told TASS.

"The 40-day war in Iran, as it is called by Iranian specialists, has ended in a fragile balance. Given the colossal gap between military capabilities of the United States and Israel on the one side and Iran on the other, we see that the attacking party is ready to continue the war without significant military losses while the Iranian military and political leadership is ready rather to die than surrender," said Adlan Margoyev, an expert on Iranian affairs and a researcher at the Institute of International Studies at the Russian Foreign Ministry's Institute of International Relations (MGIMO University).

According to the expert, a ceasefire in the absence of a peace treaty "looks like extra time to the United States to think which of its objectives are realistic and whether it is in its interests to pay a high economic and political price for the." "Washington believes that time is on its side while Tehran is sure of its endurance, and no one is going to change his positions. That is why the talks are not proceeding smoothly," he added.
