It's not true.
The thing is deception and all its shapes are forbidden in Islam, but as I explained, if there is a personal harm to you, or your country, you can deceive them, especially in wars.
But if there is no harm, deception is forbidden.

9|4|Excepting those of the idolaters with whom ye (Muslims) have a treaty, and who have since abated nothing of your right nor have supported anyone against you. (As for these), fulfill their treaty to them till their term. Lo! Allah loveth those who keep their duty (unto Him).

One more thing, Islam is very clear; it does not need deception from any kind to prove something or to show power!
Islam is logically, scientifically, powerfully enough to treat with all with no deception
