When it comes to political negotiations and leaders involved in this conflict, the list is many. For many years the argument has had its heightened tensions and more peaceful times. This will break this down into timelines.
In this time era, talks of peace were arousing. As the devastating 1967 war left Israel with much more land, they used this as a bartering chip for a peace treaty. They rejected two treaties as a result of insufficient security. Israels withdraw from Lebanon only occurred after the invasion and through an agreement of withdrawal from Syria as well, but that was not met when Syria did not withdraw.
The Oslo process was a huge step forward for the peace of the middle eastern conflict, as a trade for Palestinian freedom for Israeli's safety in security. As it was a great plan, radicals made it very difficult to produce a full agreement. Syria also talked peace to Israel, but they could never find proper terms that both parties agreed upon.
Advancements in peace starting with Israel and Jordan were made. They officially signed a formal peace treaty with Israel, making them only the second middle eastern country to do so. Also, The leader of America, Israel, and Palestine all went on a walk together to talk peace. They put many things out on the table, but could not totally find common ground yet. This act is still a big advancement in peaceful relations.
Saudi Arabia is now talking peace to the Israelis, but the Israelis are questioning their credibility based upon the Palestinian refugees. Major western and European countries came together to talk about security. This act made president Bush the first American president to side with Palestine instead of Israel.
The United States made big advancements with peace between the Israeli and Palestinian relations, creating a joint understanding of the two powers. After Barack Obama became the American president, he heavily sided with Israel, but gave the proper necessities needed to the Palestinian people to ensure long-term peace between the two powers.
