So I just played an interesting round as Poland. I got the Polish-Lithuanian Commonwealth back (I regret not being able to be bilingual, but they'd be overthrown by totalitarians otherwise), and I got the historic land back (I'll admit I used cheats here, since there's no way to do it peacefully at this point). Then I found myself at war with France, Spain, and Britain (RSI had dropped Syndicalism and joined the Federation).
The Spaniards helped the French keep the war at a stalemate, and I hardly had a big enough army to make a difference. Then I noticed that Germany was getting the crap bombed out of its industrial centers, and it was doing little to stop the British marauders. This would not do! So I built several wings of interceptors and set them on Air Scramble at all regions with large amounts of IC. I also built up AA and Radar in Warsaw, Lodz, and Kaunas, since they kept taking cheap shots at me (and only having 71 base IC means you can't afford to lose a lot, especially when building up an air force).
The defensive stance was successful in that I preserved both our IC. But it was still a stalemate. By 1943 I knew it was up to me to be the tie-breaker. But how? I only have 5 divisions on the front as a token support force, and my army was obsolete. That's when I decided to see if the Syndies could take what they were dishing out. I set about researching and building strategic bombers. I created 12 in all divided into 4 wings of 3. It took awhile, and I didn't get my last set until late 1945.
I started out by bombing Paris. I quickly learned that the French could do little to stop me. British interceptors would occasionally catch me, but about 50% of the time the escort fighters were able to drive them off. Soon 21 IC was turned into 0. A few months later, I discovered that my bombers had the sufficient range to literally reach any province in France. Rallying all available planes, I took to the skies, vowing to leave no factory unburned! My campaign of epic carpet bombing was a resounding success, with only a few interruptions due to accumulated damage. By the dawn of 1946, France's base IC had dropped from 180 to 10. They began experiencing massive supply shortages (Britain picked up the slack for a short time before I started carpet bombing them, too), and this was the edge the German's needed to break through. Just in time, too; the Communards had just made headway into Alsace-Lorraine.
Progress was slow for several months, but I kept the bombs falling steadily day and night, smashing every factory my bombers could catch in their sights. Finally, during the late summer, the Commune's army began collapsing. The army's size had been halved from 160 infantry to 82 during the first big supply shortage, but they were able to hold the Germans at bay (since I see that manpower has been buffed for the French), and the Reichswehr kept getting itself encircled and crushed. The constant lack of supply eventually won out, though, as their numbers continued to decline in an effort to conserve usable IC. Hell, my token army was even able to act as a spearhead into Spain before the year was out! As I post this, France and Spain are in ruins. Portugal has been liberated with a new king, but the Spain annexation event hasn't fired yet.
Right now the Brits are taking the full force of my aerial wrath. I hope to starve out their ships and airplanes (one of my bomber wings is constantly cratering the runways; I'm going to start on their ports when I play next). There hasn't been a British air sortie in a long time; I think most of the RAF is too badly damaged to fly, since they now only have 8 or so IC from all the bombing, so they can't repair whenever they get mobbed by my interceptors. I plan on constructing a few fighters to secure air superiority, as well as some transports and paratroopers. My hope is that the Germans will start landing troops if I open up a spot for them.
