IN Iran, elements from within the regime are reportedly offering a $US1 million ($1.5 million) reward for the assassination of Egyptian President Hosni Mubarak because of his opposition to Hamas in the Gaza Strip.
In Lebanon, the leader of Hezbollah, backed by Iran and Syria, merely calls for the Egyptian Government's overthrow.
In response to this, the editor-in-chief of the Saudi newspaper Al-Sharq al-Awsat, Tariq Alhomayed, describes Hamas as Tehran's tool and argues: "Iran is a real threat to Arab security."
Egyptian Foreign Minister Ahmed Aboul Gheit agrees, and he is not alone. When Arab states met to discuss the Gaza crisis, Saudi Arabia vetoed any action. Even the Palestinian Authority blames Hamas for the fighting.
Activists in Hamas's Palestinian rival Fatah, which runs the authority, make no secret of their hope that Hamas loses the war.
Welcome to the new Middle East, characterised not just by the Arab-Israeli conflict, but by Arab nationalists versus Islamists.
Recognising this reality, the Palestinian Authority and virtually all the Arab countries other than Iran's ally Syria, want to see Hamas defeated in the Gaza Strip.
Given their strong interest in thwarting Islamist revolutionary groups, especially those aligned with Iran, the Arab states are not inclined to listen to the "Arab street", which is far quieter than it was during previous conflicts, such as the 1991 war in Kuwait, the 2000-04 Palestinian uprising or the 2006 Israel-Hezbollah war.
Today's Middle East is very different from the old one in many significant ways.
First, the internal politics of every Arab country revolves around a battle between Arab nationalist rulers and a radical Islamist opposition.
In other words, Hamas's allies are the regimes's enemies.
An Islamist state in the Gaza Strip would encourage those who seek to create similar entities in Egypt, Jordan and every other Arab country.
A tremendous price has been paid in lives and treasure for this nationalist-Islamist conflict.
The violence has included civil wars among the Palestinians and Algerians, massive bloodshed in Iraq and terrorist campaigns in Egypt and Saudi Arabia.
In the Palestinian case, after winning an election victory and making a deal with Fatah for a coalition government, Hamas turned on its nationalist rivals and drove them out of Gaza by force.
In return, the Palestinian Authority has been repressing Hamas in the West Bank.
In Lebanon, Hezbollah has been trying to bully its more moderate Sunni Muslim, Christian and Druze rivals into submission.
And because the Arab states confront an Iran-Syria alliance that includes Hamas and Hezbollah, in addition to the internal conflicts there is a regional battle between these two blocs.
A major aspect of this power-struggle is that the largely Sunni Muslim-led states face a largely Shia Muslim-led competitor for regional hegemony.
These two struggles pose far greater dangers to the existing states than does any (largely fabricated) Israeli threat, and the region's rulers know it.
On the other side of the divide, Iran and its allies have put forward the banners of jihad and "resistance" to the US and Israel.
Their platform includes Islamist revolutions in every country; Iran as the region's dominant state, backed up by nuclear weapons; no peace with Israel, and no Palestinian state until there can be an Islamist one encompassing all of Israel as well as the West Bank and Gaza Strip; and above all the expulsion of Western influence from the region.
This is a highly ambitious program and probably impossible to achieve. Nevertheless, it is a prescription for endless terrorism and war.
Both pro-Iranian and anti-Iranian Islamists believe that because God is on their side and their enemies are cowardly, they will win -- and they are quite prepared to spend the next half-century trying to prove it.
Although this seems to be a pessimistic assessment of the regional situation, the radical Islamist side has many weaknesses.
Launching losing wars may make Islamists feel good, but being defeated is a costly proposition, because their arrogance and belligerence antagonises many who might otherwise be won over to their cause.
And the situation provides a good opportunity for Western policy makers.
The emphasis should be on building coalitions among the relatively moderate Arab states threatened by radical Islamist forces, and on working hard to prevent Iran from obtaining nuclear weapons, a goal that is in the interests of many in the region.
The worst mistake would be to follow the opposite policy, making an inevitably futile effort to appease the extremists or seek to moderate them.
Such a campaign actually disheartens the relative moderates who, feeling sold out, will try to cut their own deal with Tehran.
The crisis in Gaza is only one aspect of the much wider battle shaking the region.
Helping Hamas would empower radical Islamism and Iranian ambitions, and undercut the Palestinian Authority and everyone else, not just Israel.
Arab states don't want to help their worst enemy, so why should anyone else?
