We did get hit, but not hard enough. Guardians keep almost 100% air during peace time and when we go blitz we were able to counter to get air superiority quickly. After second update we pretty much had air superiority on all nations that attacked us, they even had to call in SK for our upper tier. They just didn't put enough bodies on us.
I didn't have a military to begin with so yeah... but the war is still young, I have feeling i'll add another 40k infra destroyed to my stats before this is over
