Historically it has been a mix of both, Israelis and some soy-neocons love to say that Israel "won" every war (numerically only really.) take the 2nd lebanon war for example we sent troops to get ambushed for no reason, our military was so incredibly incompetent we achieved nothing really major in that war and hezbollah is still a threat to this day, yom kippur parallels to this day are incredible due to, intel, lack of immediate reporting in spite of intel, incredible over-confidence and not taking the enemy seriously, sure we are probably gonna counter with hells fury and some jewish wizardy but it still shows a serious lack of military competence, Yom kippur was the same thing we knew everything that happened and just let it happen for no reason people will say glow in the darks but yom kippur directly made golda meirs government collapse but this will only make bibi stronger imo since the sephardics are inlove with their monarch and they make the jewish majority.
