Such arguments can be used to justify huge issues such as war. Here is an example:
If you examine the record of the so-called the anti-war movement in this country and imagine what would have happened had its counsel been listened to over the last 15 and more years, you would have a world in which the following would be the case…
Saddam Hussein would be the owner and occupier of Kuwait, he would have succeeded in the annexation, not merely the invasion, but the abolition of an Arab and Muslim state that was a member of the Arab League and of the United Nations. And with these resources as we now know because he lost that war, he was attempting to equip himself with the most terrifying arsenal that it was possible for him to lay his hands on. That's one consequence of anti-war politics, that's what would have happened.
In the meanwhile, Slobodan Milosevic would have made Bosnia part of a greater Serbia, and Kosovo would have been ethnically cleansed and also annexed. The Taliban would be still in power in Afghanistan if the anti-war movement had been listened to, and al-Qaeda would still be their guests. And Saddam Hussein, with his crime family, would still be privately holding ownership over a terrorized people in a state that's been most aptly described as a concentration camp above ground and a mass grave underneath it.
