Naw, the American military has always been 70% Republican since the end of the Vietnam war. Also keep in mind Democrats are probably 75% women. The Democrat men cannot be saved. This ultimately means something like 15K Republican men joined the army so they could pay their bills. It sucks that impoverishment is a major recruiting strategy, but this also means our side needs to come up with solutions for men who need income if we want recruitment to fall to sub-10K.
Military as a whole is historically 70-80% Republican but that isn't applicable evenly across the force
Combat arms as a whole, SOF especially, the USMC, the Army, and the enlisted ranks lean to the right of the military-wide average which means the officer corps, Air Force/Navy, and non-combat positions are on average to the left of the armed forces as a whole.
In terms of recruiting young white conservative or right wing men, a few thoughts:
1. I don't think the "young men don't want to die for Israel" meme is actually a major factor.....the types of young men who are inclined to join combat arms in the first place want to go to war and for better or worse aren't particularly picky about whether or not they're going to "fight for Israel". Recruiting of those types of men isn't cratering because of forever wars, it's cratering because we AREN'T actually at war right now--GWOT is over which means far fewer opportunities for adventure for young men. Dying for Israel may be an issue affecting other services or non-combat MOS', but while there's no real way to measure it I highly doubt it's having an impact on combat arms recruitment....quite the opposite in fact.
2. While I greatly appreciate the shock to the system the current recruiting crisis is providing, I've never been fully on board with the "no young RW/traditional/conservative/whatever you want to call it man should ever join the military no matter what" thinking. For one thing, the benefits the military provides are unmatched--most of all the VA home loan which is a cheat code for getting started in building wealth but also everything from learning a trade to real world combat experience to the GI Bill. Second, it benefits our movement to have people in place in the military (and yes, this means they'll need to swallow their tongue at times and go along with leftist nonsense in pursuit of the greater good), and it also benefits our movement to have people go into the military, get training and experience, and come back to their communities.
3. It would need to be done carefully so as not to attract attention, but I'd like to see the RW make a concerted effort to push young men towards the Coast Guard. You get all the same benefits as the other services, the types of jobs are more or less the same as what the Navy has, and you're actually protecting your community (yes USCG ships can legally be sent overseas to augment the Navy but as far as I'm aware it hasn't happened since Vietnam, and the Navy outside of SOF and air power is directly involved in a conflict there's a decent chance it's actually in the country's interests anyway or at least not directly opposed to them). There are opportunities for kinetic action with drug intervention and the like along with other opportunities for adventure of the type young men are drawn to--jumping out of a helicopter into Lake Superior in October to pull some boomer out of his sinking fishing boat might not be the same type of adventure as kicking in doors in some Middle Eastern hellhole, but it's still adventure.
