Ahmadinejad cannily talks to Western audiences about the supposed evils of Zionism in an attempt to isolate Israel. The Western press eats it all up, of course, because it makes good copy.
This plan has been in place since the infamous Tehran conference in October of 2005 called "A World Without Zionism." But what doesn't get reported was the name of the October 2004 conference - "A World Without America." Here was its logo:
In the poster for the World Without Zionism conference, an hourglass is shown where the Israeli ball is falling - and the American ball is already on the bottom of the glass, broken:
Also at the World Without Zionism conference, Ahmadinejad said, "They [ask]: 'Is it possible for us to witness a world without America and Zionism?' But you had best know that this slogan and this goal are attainable, and surely can be achieved."
The US press is simply ignoring the threats that Iran has made against America and focused only on Israel. But Iran's goals are clear and have been for years: to create a superpower to not only rival but to defeat America, by not only uniting the Muslim world but also by obtaining nuclear weapons.
See my posts here on how the MSM is wrong on Iran, here on a collection of Ahmadinejad's statements, here on his threatening the free world, this post comparing his methods with Hitler, and this early 2006 post on Iran's plans which is still relevant (as well as its own links to earlier postings.)
