On Wednesday, Israel successfully test-fired a missile said to be capable of carrying a nuclear warhead and striking Iran, adding to the debate over whether Israel's leaders are considering a military attack on Tehran's weapons facilities, according to CNSNews.com. Israeli officials have long warned that a military strike was an option, and this week Prime Minister Benjamin Netanyahu expressed new concerns about Iran's nuclear program. Wednesday's missile launch, from a base on the outskirts of Tel Aviv, added to the speculation that Israeli action could be imminent. Israel considers Iran its most dangerous threat; Iran has repeatedly referenced Israel's destruction and voiced support for anti-Israel militant groups Hamas and Hezbollah. "What Israel would wish to see is that the United States and rest of powers would pressure Iran more seriously ... first with more sanctions and if they don't work, to go to war with Iran," said Eldad Pardo, an Iran expert at Jerusalem's Hebrew University. In the case of any attack on Tehran, Iran's military leaders say they will "punish" Israel.
