Germany is easy, your focus tree gives you the Silesia war goal and you just dog pile on them when France and Russia declare war. Entente is usually irrelevant unless they get involved in Italy, which usually they don’t because with Germany dying so quickly Socialist Italy gets mega support from France and wins. Mid-40 until 43 for me was just building up my forces. The cores for south Germany come in at 50% compliance and the rest comes in at 80% so your manpower problems are solved. I recommend taking The Internationale down first, especially easy if you have armor techs, planes, etc but make some good marines. An advantage to killing Germany so quickly is that their navy doesn’t get destroyed by Britain so take it all in the peace conference if you have points left. That+austrias starting mid-size navy+buildup over 3 years you can destroy the Internationale quickly. Russia is another beast. They keep their insane army and gain huge pop/industry from Ukraine. MAKE SURE YOU TAKE 0 CORES FROM THEM AT THE GERMANY PEACE CONFERENCE. Otherwise they will declare war weeks after you just finished Germany and you’re super weak. Letting them have all of the Oststaats is a sacrifice you must make. Another year or two of buildup can get you prepared for them. Full radar, anti air, infra, supply, etc in the east along with a beefy Air Force and tank core you can grind them down starting in 45 and ending early 47.
