What are the causes of the Iranian-Israeli Proxy Wars?

Answer 1

Iran and Israel are the two major regional powers in the Middle East, however, Israel has consistently maintained the top position. This has resulted in Iran wishing to take hegemony away from Israel and become the dominant power in the Middle East. To this end, Iran has supported the Syrian Alawite Government (Bashar Al-Assad), the Terrorist/Paramilitary Organization of Hezbollah, the Terrorist/Paramilitary Organization of Hamas, and several other groups intending to weaken Israel and its position. Iran has consistently stated that it believes that Israel is a cancer and must be wiped off the face of the map (even though they make it clear that "they will not do the wiping"). Using these secondary forces to oppose Israel makes it appear like Iran is a peaceful country since Iran did not declare war on Israel, Hezbollah did or Hamas did. It gives Iran an odd deniability.

Israel has responded by killing Iranian nuclear scientists and consistently derailing Iran's nuclear program. Israel has focused its energy in defending its borders and trying to contain retaliation to its source, not the proxies.
