Do you know what happened just before the soldier was captured? A Palestinian family on a beach were shelled for the crime of just being there. It was an "accident." There are no isolated incidents. Merely a continuing stream. 
So in essence what you are saying is that it is acceptable for country "C", Lebanon through Hezbollah since they do have representation in the government, to retaliate against country "B", Israel, for something that allegedly happened to country "A", Palestine? If we go by your logic here, it would be perfectly acceptable for France to kidnap a Brit and hold him until the UK agrees to release all IRA members they currently hold. Or Germany to bomb Spain for killing anyone associated with the ETA.
While I've never been a big fan of Israeli tactics, if I were in the shoes of their government and a group from a neighboring country kidnapped one of my soldiers, anyone that associates himself with that group had better do two things. Run far and fast, for he just painted a target on his back.
One thing I've never understood about these idiots. If my next door neighbor has kicked my ass anytime I tried to start a fight with him, the last thing I'd do is kidnap one of his kids and then let him know about it.
Apart from Israeli threats to them... Hezbollah's involvement is kind of "unknown" we don't know who started it. Was it the bombing of lebanese targets that had Hezbollah forces fight back?
As for Palestine, Israel killed loads of innocents. Everytime it killed a militant leader atleast 10 to 15 innocent people were killed and wounded. Holding the soldier hostage was'nt the Palestinian military. And should we forget what happened about 3 months ago? A Palestinian criminal in a palestinian jail was arrested and forcibly extradited under tank fire and shelling killing prisoners and a security gaurd. Palestinian government asked for american help and the americans just stood by and did nothing. Infacth that anywhere else is a declaration of war. Palestine is a soverign democracy. And fair and square hamaas is in power. And what they did is the same thing as the Israelis. Except how many Israelis are in jail for terrorism. If you look at it for revenge most of them just want the women and children held in Israeli Jails released. Its not asking for the men. Its asking for children and women.
The hundreds of rockets are about as dangerous as a bottle rocket. There is no guidance system and infact the only death was from a hezbollah rocket which is more advanced and using professional warheads. Three death from all those attacks. Unlike the attacks on Palestine...
Palestine cannot protect itself. Its not strong enough and its fragmentted. The people who promised to protect it are'nt doing their job (It is technically a UN protectorate. USA and British observers were placed to ensure Israel does'nt break mandate... Blind eye to the transgressions.) So who will protect the palestinians? The west won't so their neighbours must. For example if switzerland is being attacked.
The situation is'nt as you described. Technically Israel is the palestinian land. Palestinians were forced off it by the west to allow jews in. The palestinians attacked for their land back. Israel had more mordern weapons and won. Palestine was constantly ghettoised until its current state. Thus creating a special kind of irony. That the people who knew the stigma of ghettos have gone and done the same thing to someone else. Instead of pogroms the Israelis now use air to surface missiles. So in this case the neighbours who are the same people as Palestinians share sympathy. Just as Jews across the world shared sympathy for the germans. So they responded as the people who had promised to protect palestine came up trumps. Palestinian terrorism is the resort of someone who does'nt have the money to afford arms. Its the only way they can defend themselves. Do you want them to go back to their tit for tat attacks on civilians? Atleast their suicide bombing has ground to a halt playing by the book.
The IRA and Palestine are in different leagues of greiviance. For start NI does'nt exist at the hands of people who control whether they live or die. The english people don't go there and force irish people out of their houses to live in them. The comparison is bunk. Palestinains at this point have no power, no water, no food and no medicine. Northern Ireland... Is paradise compared to their living conditions.
