What figure of speech is this and what is its purpose?

The U.S. invasion of Iraq, it seems, was not enough for the Israel-firsters. Now, according to Sen. Joseph Lieberman, a U.S.-launched war on Iran is needed because "the threat that the U.S. and Israel face from the Islamic Republic of Iran is today greater than ever." Though based on the fantasy that Ahmedinejad's tin-pot regime is a threat to the world's only superpower, this is a perfectly commonsense position for Israel and its U.S.-citizen backers in AIPAC to champion. In their view, U.S. wars with Muslims are the ultimate good for Israel. Recall, if you will, the perfectly accurate April 2008, words of Benjamin Netanyahu, likely Israel's next prime minister: "We [Israel] are benefiting from one thing, and that is the attack on the twin towers and the Pentagon, and the American struggle in Iraq." These wars, Netanyahu said, have "swung American public opinion in our favor." How much more must Netanyahu and AIPAC believe that a U.S. war with Iran would add to this "swing" in Israel's favor?


To what does this question serves exactly? To put an emphasis on the fact that it is impossible to believe more, to a greater extent that a U.S. war with Iran would add to this "swing" in Israel's favor?
