(CNN) -

As rockets and missiles fly across the Israeli-Gaza border, CNN's Ben Wedeman describes the mood on the ground in Gaza.

Is there a mood for war in Gaza?

No. Among people with no affiliation with one faction or another, there is little enthusiasm for this flare-up. People here are exhausted. They see no benefit whatsoever of firing missiles into Israel that result in airstrikes that are extremely disruptive to daily life.

Keep in mind that last summer after the overthrow of the Morsy government in Egypt, many of the tunnels under that country's border with Gaza were destroyed, so the economy is in abysmal shape.

Most Gazans would like to see an immediate return to peace. They're frustrated that since 2006 when Hamas won elections and took over, Gaza has been under siege. It's very difficult to leave here ... it's very difficult to earn a living, therefore few people are supporting this flare-up.

Are people supportive of Hamas?

Hamas is defiant, saying the blood of the martyrs will be fuel for the Intifada. On Monday night it claimed responsibility for 60 missiles fired into Israel. They're on a war footing.

Hamas is blaming Israel for the current flare-up but it's not putting out any olive branches. They're going to contribute firing missiles into Israel until there's some sort of cease-fire.

In November 2012 the Egyptians were able to intercede between Israel and Hamas and that led to a ceasefire, but now you have a very different government in Cairo that is hostile to Hamas and seems uninterested in intervening and bringing calm to Gaza.

What is the attitude towards Israel?

The majority of people in Gaza are the descendants of those who were driven or fled from their homes in 1948-49, some from the very same areas currently being hit by rockets from Gaza.

There is a deep sense of loss, of dispossession which is particularly intense in times of conflict.

One man told me today "I hope they bomb the Knesset," referring to the militants firing rockets. Another outside a house in Khan Yunis that had just been struck by a missile that left seven dead told me "the Israelis have been killing us since I can remember. And they will continue to kill us after I die."

Are there dissenting voices critical of Hamas in Gaza?

Yes there are. Many people you speak to are opposed to it because all the rocket firing does is make the situation worse.

One man I spoke to said: "Of course we dislike Hamas and want them to go, but if I were to say that in public there would be trouble for me."

Obviously there are few dissenting voices in public; privately there are many. The only real opposition to Hamas is Fatah, but that faction that is dominant only in the West Bank, not in Gaza.

Why has this flare-up happened now? Is it about more than just the tit-for-tat killings of the Israeli and Palestinian teenagers?

In the aftermath of the Israeli teenagers kidnapping on June 12, Israeli officials made it clear they were operating in the West Bank and elsewhere on a two-track approach. On the one hand they wanted to find the boys and catch the kidnappers; on the other they were cracking down on Hamas. That's certainly set the tone.

But you have go back to April 1 when Palestinian Prime Minister Mahmoud Abbas announced there would be a unity or reconciliation pact between Fatah and Hamas.
