The Israelis see the union between Fatah and Hamas as an impunity, while Palestine sees the unity governance as a solution to a problem of separation. The rockets flying in and out of Gaza are a result of this union, and Israel will continue the defense. Fatah accepted a terrorist organization into their government, even further provoking Israel to take action to defend their people at the threat of destruction. Both nations are on high alert as the situation continues to be increasingly dangerous as one is pit against the other as a result of media coverage.
The creation of the unity government in Palestine called for open parliamentary elections that does not specifically delegate candidates as part of the Hamas or Fatah party. Mainly, they differ on how the government should be run, but also they heavily differ on their stance on Israel. Hamas hates everything about the nation, Fatah wants Israel to stop calling itself a Jewish state.
This new Palestinian government presents further troubles for Israel. Parliamentary members could very well have supported terrorist actions against the Jewish people or other Israelis and continue to present danger to the neighboring country. All of this has a negative effect on the economics and lives of Israelis, as well as destruction of the Gaza strip. Recently, Qatar offered millions to help rebuild Gaza, but more than likely given it’s background with the Muslim Brotherhood, backs Hamas and Palestine and wants the same of Israel as Palestine. The parties within the Palestinian political picture aren’t like those here in the US; they both are very rash with decision making and have reached a breaking point.
