TIBERIAS, Israel - Will there be a war in the Middle East this summer? That's the question many are asking.

Israel recently held its biggest nationwide drill in history to prepare for the possibility of war -- a thought never far away from the minds or lips of most Israelis.

"We discuss the fact that we hope it never happens and what we're going to do if it does happen and the thought of it is terrible," one resident said.

The threats surround Israel. There are scud missiles in Syria, and as many as 5,000 rockets in the hands of Hamas on Israel's southern border, despite efforts of a naval blockade to keep the weapons out. And to the north, it's now estimated Hezbollah possesses more than 40,000 rockets aimed at the Jewish State.

During the 2006 second Lebanon war, the range of most of Hezbollah's rockets ended in the city of Tiberias on the sea of Galilee. Now, intelligence experts warn Hezbollah rockets could hit anywhere in Israel.

There are also two wildcards in this dangerous chess match. Turkey - once Israel's closest ally in the region -- is now a possible adversary and Iran is close to going nuclear

"I think that the main threat is still Iran," said retired Israeli Gen. Yaakov Amidror, adding that the country is still the power behind most of Israel's threats.

"It is not only the nuclear, it's the fact that Iran is behind Hezbollah. Iran is behind Hamas  in the same way," Amidror said. "Iran is helping Syria. And only by neutralizing Iran, can Israel feel that it has enough security."

But could Israel eliminate or significantly slow down Iran's nuclear program on its own?

"Israel should be prepared to deal with Iran by itself. How long it will take if the decision will be taken at the end, this is a huge question mark," Amidror added. "Knowing my colleagues in the military, I am sure that Israel will be fully prepared when the government will make the decision."
