I don't see a contradiction.
It ends with a plea for a narrower policy ,-- to target "as a laser beam" Osama bin Laden and the Taliban. The bulk of the article argues against a wider policy, and in particular pleads not to target any nation that may happen to be Israel's direct enemy. How does it argue? Solely by noting that the proponents of the wider policy are neo conservatives.
A proper argument against any policy should discuss the merits of the policy, not political groupings. This one doesn't. That is the contradiction you don't see, between the stated support of the general policy and the content of he article.
