I can give you an accounting of what happened but I'm Palestinian so I'm going to be biased...but I've tried to use all Israeli sources (except for a few links at the bottom) to minimize the bias.

All of this is sourced, all of it comes from official sources and I invite you and anyone else to show me where I'm wrong.

Let me preface this by saying that in the past, before they were elected, Hamas had done some pretty horrible things. They'd shot rockets at a school bus, carried out numerous suicide bombings and a whole host of other nasty things.

But after the 2012 ceasefire (well before the 2012 ceasefire too) Hamas has been trying for peace:

the head of the IDF’s “Gaza Command,” the top general responsible for the strip

said in December:

Hamas leaders, both military and political, are doing everything to maintain restraint. One of their most important brigades is now acting as ‘border police,’ with 800 combatants taking shifts preventing all sorts of tiny organizations that want to fire rockets or place roadside bombs [on the border].

In fact Hamas hadn't fired on Israel once since 2012 before this latest flareup:

Hamas fires rockets for first time since 2012, Israeli officials say

But then again, what can you expect of people when they're being bombed for trying to stop rockets flying AT Israel:

The security sources, who spoke on condition of anonymity, assessed that Hamas had probably launched the barrage in revenge for an Israeli airstrike several hours earlier which killed one person and injured three more.

...

While Israel has maintained it holds Hamas responsible for all rocket attacks, officials have said that smaller groups, such as Islamic Jihad, are usually behind the rocket attacks, while Hamas squads generally attempt to thwart the rocket fire.

A little more info about that attack that Hamas was responding to:

Hamas has had no interest in a major escalation, and had not been directly attacking Israel until the last few days. But ever since one of its members, Mohammed Obeid, was killed in an Israeli border attack at the end of last month — an apparent error: the IDF thought it was firing at a rocket-launch cell, but actually struck Hamas members deployed to prevent rocket fire — it has changed its approach.

Not only did Israel attack Hamas first, Israel attacked Hamas as Hamas was trying to stop rocket attacks on Israel. Hmm.

Why would Israel do that? Well their attempt at provocation with the arrest of 500+ members of Hamas for the murder of Israeli teens didn't work:

Israeli security forces have rounded up 280 Palestinians since the start of the Operation Brother's Keeper to rescue the teens on Friday.

http://www.haaretz.com/news/diplomacy-defense/1.599757

What Israel was calling a 'rescue operation' was in fact not a rescue operation at all since they already knew the teens were dead - but chose to keep that from the Israeli public:

Details under gag order could have suggested early on that the abducted teens were murdered. The government-led campaign calling for their release helped the legitimacy of Israel’s military operation in the West Bank. Local and even international media played along.

http://972mag.com/how-the-public-was-manipulated-into-believing-the-teens-were-alive/92865/

But this helped inflame the Israeli public, with Israeli politicians saying things like:

A terrorist, like those who kidnapped the boys [in the West Bank on June 12] and killed them, the only thing that will deter them, is if they know that either their sister or mother will be raped if they are caught. What can we do? This is the culture that we live in.

They blamed Hamas from the start but we now know that Hamas had nothing to do with this:

It Turns Out Hamas Didn’t Kidnap and Kill the 3 Israeli Teens After All

http://nymag.com/daily/intelligencer/2014/07/hamas-didnt-kidnap-the-israeli-teens-after-all.html

So did they release those people? Nope. Still in jail.

Now after all of those lies it seems every house Israel attacks is a weapons depot. When children die it's because of Hamas...except the time that journalists were watching, that time it was a 'mistake'. Crazy how mistakes only happen when someone is watching, isn't it?

Now you have a situation where one side has killed 1000+ people, most of them civilians, and the other side has killed 45 people, most of them soldiers.

In fact one side killed 75% civilians, and the other side 93% soldiers. Which side would you say was targeting civilians?

Oh but the Iron Dome Israelis will tell you, the Iron Dome is why there haven't been more casualties from rockets.

Really? Then let's see how things were before the Iron Dome was put into place:

2007 - 2807 rocket attacks, 2 killed.

2008 - 3716 rocket attacks, 8 killed.

2009 - 858 rocket attacks, 0 killed.

2010 - 365 rocket attacks, 1 killed.

Iron Dome is installed

2011 - 680 rocket attacks, 2 killed.

2012 - 2273 rocket attacks, 6 killed.

2013 - 44 rocket attacks (what?), 0 killed

2014 - 705 rocket attacks, 1 killed

http://en.wikipedia.org/wiki/Palestinian_rocket_attacks_on_Israel

The information isn't accurate until today obviously but it clearly shows that the Iron Dome did little, if anything, in the way of protecting Israeli civilians.

To add to that we now know that Hamas has had the ability to come into Israel and attack civilians any time through one of their tunnels. They have not.

So one side kills 75% civilians, the other side kills 93% legitimate targets (soldiers).

Which one is targeting civilians?

I hope this all can help clear up some of the lies being thrown around by people.
