Investing in US Defense Manufacturing stocks seems to be a good value bet for mid-long term amid rising global conflicts and increased military budget. Thoughts?

If you have kept up with international news for past few years, then almost every few months we have a new conflict which pops up in some part of the world and honestly, the US government and/or the military-industrial complex is always involved in some or the other way. Either they directly enter the conflict zone (like in Venezuela or by bombing Middle east countries) or indirectly via supplying ammunitions as in Ukraine (RTX Corp. for example had a lot of orders for their Patriot air defense system in past years). On one hand it creates an uncertainty in global markets (except S&P 500 which seems to only go up!); it also seems logical to allocate part of your portfolio to pure play US defense contractors. **And while nobody wants war (obviously), the cold hard truth for investors is that heightened geopolitical risk = sustained/increasing defense budgets, especially in US where govt. spending is bottomless pit. The recent announcement by POTUS of a 50% increase in the US military budget from the next year itself is a testament to that.** The total budget will become $1.5 trillion, and the additional capex means even more orders for these companies to their already huge orderbook. My 3 picks to play this sector would be--> 1. General Dynamics Corporation ($GD): Diversified revenue streams; from Abrams tanks, Virginia class submarines, military cybersecurity/IT services to Gulfstream business jets for VIPs. Also, their valuation is the lowest amongst their peers. 2. Northrop Grumman Corp. ($NOC): B21 bombers; component manufacturing for F35s; satellites/stealth systems etc. 3. Lockheed Martin Corp. ($LMT): \~50% of their revenue comes from fighter jets/helicopters (F35, F22 and Blackhawk) while remaining from missiles, space systems, radars/detection systems etc.
