The propaganda that claims Netanyahu's family origin is Polish is partially true but it was Russian occupied Poland, his earliest known family origin is from Russia, in particular the Belarus and Lithuania former Russian regions, the further you look the more Russian he gets.

ごめん、誰か知ってたら教えてほしいんだけどギリシャ神話にイカロスっていたじゃん? 太陽に近づきすぎて、蝋で作った翼が溶けちゃった人。 だけどさ、実際のところ、地上から上空に向かうとどんどん気温って下がるじゃん? 飛行機に乗ってる時ってだいたい高度約10,000メートルの上空にいるけど、あそこまで上空に行くと外気温がマイナス40度とかになるじゃん? 熱源であるはずの太陽に近づいているのに、なんで気温は地上よりも下がるの? ってかイカロスは太陽に近づいて蝋の翼が溶けたはずだけど、上空って寒いから溶けなくない? それとももっと上に行けば、気温は上がるの?どれくらい上に行けば蝋が溶けるレベルの気温になるの? 対流圏?成層圏?それとも電離圏ぐらいまで行かないと無理? でもそこまで行ったらもう空気がないから呼吸できなくね? じゃあ、イカロスはどうやって「蝋でできた翼」が溶けるくらい高温かつ上空に行ったの??
