JERUSALEM, Israel -- Several senior Israeli political and military leaders have spoken out publicly in recent days about the need for a credible military threat against Iran.
In the U.S., the Washington Post reported that Defense Secretary Leon Panetta believes Israel will strike Iran in April, May, or June.
President Obama said he believes Israel hasn't made such a decision.
Other international leaders, such as U.N. Secretary-General Ban Ki-moon, want a diplomatic solution.
"These -- all pending issues -- should be resolved [a] peaceful way through dialogue," Ban said recently. "There is no alternative to a peaceful resolution of this issue."
"We have basically advised strapping on the six-shooter not pulling the trigger yet," former CIA Director James Woolsey said.
Woolsey's advice is get ready to use force. How? By moving aircraft carrier groups and planes into position to take on Iran's nuclear program and its Revolutionary Guard.
Woolsey said financial sanctions against Iran could still bite, but the West needs to speed things up.
"They should stop piddling around with this. They ought to get it done and get it done fast because that will help to bring the financial system of Iran down, which is one thing that could help in getting them out of their nuclear weapons program," Woolsey said.
But former Israeli Ambassador Yoram Ettinger said there's only one option.
"Anybody who wants to stop Iran from becoming nuclear should realize that the only viable option is a military preemption, which is much preferable to risking a nuclear Iran," Ettinger told CBN News.
