There are two classic propaganda narratives used by governments when it comes to keeping the public invested in any war campaign that does nothing to advance their national interests:
First, there’s the “commitment” lie, which says that once you step in to support a war effort you then must stay exponentially committed, even if that war effort is exposed as pointless. Anytime the public pulls back from that war in a bid to reconsider what purpose it serves they are ridiculed for potentially “risking lives” and setting the stage for defeat. In other words, you must support the effort blindly. You’re not allowed to examine the conflict rationally, because who wants to be blamed for losing a war?
Second, there’s the “domino effect” lie, which says that if you allow a particular “enemy” to win in one conflict, they will automatically be emboldened to invade other countries until they own the entire planet. It’s the same claim used to trick the American populace into supporting the war in Vietnam and it rarely turns out to be true. In fact, nations that engage in regional wars tend to be so weakened by the fighting that they don’t have the means to move on to another country even if they wanted to.
In the US we heard both of these narratives heading into the recent congressional vote for billions more in monetary and logistical aid to Ukraine. Neocons and Democrats worked together to force the bill through with a percentage of true conservatives fighting to stop it. Those conservatives were attacked relentlessly by the media for “helping the Russians”, but the reality that no one in the mainstream wants to talk about is that Ukraine has already lost the war...
