And who told you the IDF are incurring heavy losses?

Analyse official reports of Israel military. They are created exactly as Ukrainian military reports. Not similar, not like, not same, they are designed and created unsing one template. So, you could apply already known coefficients to official data to find out numbers close to the truth.

Also, there are a lot of videos of kike soldiers extermination around - sniper shootings, traps, destruction of vehicles - easy to find. You could count documented hits in one week and compare number with official Jewish lies.

IDK, if it is in Jewish tradition to publish obituaries one way or another, if they do that - you could also count them and compare with official numbers. May be somebody already do that, but just censored by Jewish media.

PS: JFY - official number of Ukrainian losses was stated as 30k. Real one at the time of statement was around 500k. So, just multiply official Jewish losses by 16, and you will get number close to the truth.

incurring heavy losses

INCUR; verb - "to bring an undesirable consequence upon oneself"...does heavy (life) loss (inception towards death) imply an undesirable consequence for oneself or an opportunity to be oneself?
