Mark Twain once said, “A lie can travel halfway around the world while the truth is still putting on its shoes.”
It's been a successful strategy since the Balfour Declaration was signed.
However it doesn't take into account the reaction of people who believed the assertions. People do not like being deceived and will often discount any further claims.
It also relies on being able to "control" the narrative, which was much easier when people only got their news from the MSM. Social media has changed this drastically. The IDF’S Hamas hostage schedule lie, was debunked as an Arabic Calendar within minutes.
