Should Israel declare all out war on Hamas?

Frankly speaking YES.Once there is a clear winner suffering for both Arabs and Jews will come to an END.

Why not, it won't make a difference, weather Hamas is firing at Israel now, or when there' a declaration. There's no difference there is however an unofficial war.

No, it is extremely difficult to completely eradicate Hamas, and doing so would not further Israeli interests significantly.

Hamas should combine with Hezbollah to enhance their effectiveness. AS to the "question" in the first place "israel" is a terrorist entity not a legitimate government; secondly it is the zionist terrorists who need to confront an equal force.

Yes, I think they should, every country has a right to protect herself and her citizens.Article 51 of the United Nations Charter .reserves to every nation the right to engage in self-defense against armed attacks. As Professor Alan Dershowitz has also noted, “The claim that Israel has violated the principle of proportionality -- by killing more Hamas terrorists than the number of Israeli civilians killed by Hamas rockets -- is absurd. First, there is no legal equivalence between the deliberate killing of innocent civilians and the deliberate killings of Hamas combatants. Under the laws of war, any number of combatants can be killed to prevent the killing of even one innocent civilian. Second, proportionality is not measured by the number of civilians actually killed, but rather by the risk posed. This is illustrated by what happened on Tuesday (December 30, 2008), when a Hamas rocket hit a kindergarten in Beer Sheva, though no students were there at the time. Under international law, Israel is not required to allow Hamas to play Russian roulette with its children’s lives.As the London Times said in response to this charge during Israel's war with Hezbollah, this criticism “is lazy and facile in several ways, especially in implying a moral relativism between the two sides that does not exist. This is not the contest between misguided equals that many in the West seem to see. One is the region's lone democracy, which for much of its existence has faced a very real existential threat and would like, if possible, to live in peace with its neighbors. The other is a terrorist organization, bent on preventing such a future.Furthermore, Since Hamas' stated objective is the destruction of Israel, isn't the appropriate response the destruction of Hamas? Wouldn't random missile strikes on Palestinian cities be proportionate to Hamas rocket attacks on southern Israel? Can you imagine any of Israel's critics accepting those responses?When Palestinian terrorists plant bombs at Israeli shopping malls and kill and maims dozens of civilians, would the "proportionate response" be for Israelis to plant bombs in Palestinian malls? No one in Israel believes this would be a legitimate use of force. Thus, Israel is left with the need to take measured action against specific targets in an effort to either deter Palestinian violence or stop it.What would America do if terrorists fired thousands of rockets targeting U.S. cities? After 9/11, we saw that America took the same type of action as Israel by launching military strikes against the terrorists. U.S. forces used overwhelming force and though they never targeted civilians, some were inadvertently killed. Americans believe in Colin Powell's doctrine, which holds that “America should enter fights with every bit of force available or not at all.”The United States uses overwhelming force against its enemies, even though the threats are distant and pose no danger to the existence of the nation or the immediate security of its citizens. The threat Israel faces is immediate in time and physical proximity, and poses a direct danger to Israeli citizens. More than 6,000 rockets have now fallen on Israel's cities and now that Hamas has acquired long-range missiles, more than 900,000 civilians are in danger. Still, Israel has not used its full might as the Powell Doctrine dictates. The use of force has been judicious and precise.Israeli soldiers do not deliberately target noncombatants. The murder of innocents is the goal of the Palestinian terrorists. In fact, what other army drops leaflets to warn people to leave an area they intend to attack even though it gives up the element of surprise and allows the bad guys to hide as well as the innocent to escape?I.D.F. activities are governed by an overriding policy of restraint and a determination to take all possible measures to prevent harm to innocent civilians.No innocent Palestinians would be in any danger if the Palestinian Authority took steps to stop terrorism or if the international community, especially the Arab world, had pressured Hamas to stop attacking Israel. No innocent Palestinians would be in danger if Hamas terrorists did not deliberately hide among them. If the peace-seeking Palestinians prevented the terrorists from living in their midst, Israel would have no reason to come to their neighborhoods.

It is a tragedy whenever innocent lives are lost, and Israelis have consistently expressed their sadness over Arab casualties. By contrast, when innocent Israelis are murdered by terrorists, Hamas holds rallies to celebrate the murders.

...so the Israelis killing thousands of people looking for hamas is not all out war?

i agree with rundevilrun, its nice to meet people with common sense

No. I think the entire world should declare all-out war against the Zionists. The world has tolerated their relentless butchery long enough.

Yes,as long as they don't use American made weapons
