The Power of Not Believing Lies
The success of the Ukranian warriors against their Russian foes, in the face of overwhelming odds, may be ascribed by some to "luck".
But the real reason is that the Ukranians have heavy experience with Soviet-era propaganda (that is, lies). They know how NOT to let their mental state be affected by lies, such as the implicit Russian propaganda: "Our missiles and bombs can reach every part of your country; you need to surrender now."
Sadly, most Americans and Europeans have not yet learned how to separate reality from lie, especially with regard to China and internally-generated propanganda attacks.
But, there is hope.
