Since the 1979 Iranian revolution and the downfall of the US Puppet Ruler the Shah, Iran has been an Islamic state. In that interval of time, 1979 to the present, Iran has not invaded anyone. Not once. People of all religions live in peace in Iran, even Jews, who find life so comfortable in Iran they refused an offer by the government of Israel to emigrate!
In the same period of time, Israel, a self-declared Jewish state, attacked Iraq in 1981, bombing the power station at Osirik, claiming it was a clandestine weapons factory. Subsequent examination of the ruins following the 2003 invasion proved Israel had lied. In 1982, Israel invaded Lebanon. This led to the Massacres at Sabra and Shatilla. In February 2003 Israel staged incursions into Gaza and Nablus. In September 2007 Israel bombed Syria, again insisting they were destroying a clandestine weapons laboratory. Again there was no evidence to support Israel's claims. In 2006, Israel attacked Lebanon, killing 1200, mostly civilians, several UN observers, and littering the landscape with land mines on their way out. In February 2008 Israel again raided Gaza, killing over 100. HAMAS agreed to a cease fire and kept it for 6 months until November 4, when Israel again attacked without warning, killing 6 HAMAS members, and launching operation CAST LEAD. 1300 Gazans, mostly civilians, were killed. Israel lost 13 soldiers. Violations of international law included the use of White Phosphorus incendiary bombs against civilians and non-military targets. The United Nations investigated, but Israel refused to cooperate. In May 2010, Israel attacked an international aid flotilla bringing food and medical supplies to Gaza in international waters. 9 people were murdered including an American from New York. In the same period of time, the United States, officially a secular nation but predominantly Christian, attacked El Salvador (1980), Libya (1981), Sinai (1982), Lebanon (1982 1983), Egypt (1983), Grenada (1983), Honduras (1983), Chad (1983), Persian Gulf (1984), Libya (1986) , Bolivia (1986), Iran (1987), Persian Gulf (1987), Kuwait (1987), Iran (1988), Honduras (1988), Panama (1988), Libya (1989), Panama (1989), Colombia, Bolivia, and Peru (1989), Philippines (1989), Panama (1989-1990), Liberia (1990), Saudi Arabia (1990), Iraq (1991), Zaire (1991), Sierra Leone (1992), Somalia (1992), Bosnia-Herzegovina (1993 to present), Macedonia (1993), Haiti (1994), Macedonia (1994), Bosnia (1995), Liberia (1996), Central African Republic (1996), Albania (1997), Congo/Gabon (1997), Sierra Leon (1997), Cambodia (1997), Iraq (1998), Guinea/Bissau (1998), Kenya/Tanzania (1998 to 1999), Afghanistan/Sudan (1998), Liberia (1998), East Timor (1999), Serbia (1999), Sierra Leon (2000), Yemen (2000), East Timor (2000), Afghanistan (2001 to present), Yemen (2002), Philippines (2002) , Cote d'Ivoire (2002), Iraq (2003 to present), Liberia (2003), Georgia/Djibouti (2003), Haiti (2004), Georgia/Djibouti/Kenya/Ethiopia/Yemen/Eritrea War on Terror (2004), Pakistan drone attacks (2004 to present), Somalia (2007), South Ossetia/Georgia (2008), Syria (2008), Yemen (2009), Haiti (2010), etc. etc. etc. etc.
So, who is the danger to world peace?
