Did I make an error of judgement???

I know we have spoken of this before, there are a couple of other threads concerning the violence in the mid-East. I’d like to try to avoid a flame-war as best as possible with this thread, but it seems likely that if people do reply to this thread and get involved with other replies it is inevitable, so to the Web-master and to you all I’d like to apologise in advance.
I was watching the BBC on the 4th April about the Israeli movement into pretty much all of Palestine and reports of fighting along the Lebanese border involving IDF artillery and Hezbollah (sorry if that is spelt wrong) forces. If this continues to carry on and Israel is determined to secure its territory from attack, what are the chances of Israel moving into Lebanon? It won’t be the first time and as the old saying goes “History always repeats itself!”
If Israel does move into Lebanon, could this provoke an all out war with the Lebanese Armed Forces or even a response from Syria? Egypt has reportedly cut its ties with Israel (don’t ask me about who said it – I’m hopeless with politicans names) and judging by the riots in Jordan and Egypt I am a little concerned. In previous threads I said that no nation in the region could match Israel, and I stick by this, but that doesn’t rule out the possibilty of war given the current climate. The BBC also made mention of a possible Iraqi attack on Israel via terrorism. What was suggested is that Iraq could supply a small amount of some type of nerve gas to a Palestinian group, using suicide bombers as a means of attack. Israel has warned Iraq that ANY attack on Israel will be met with an appropriate response (a possible nuclear strike on Baghdad was also mentioned by the BBC).
If the saying is true and history does repeat itself, and I hope to God it doesn’t, what a mess this could turn out to be!
