You are going to have to give more context... If that player only have 2 villages then yes, that is super sketchy but have you consider the following?
1. The player have a lot of villages that keep all barracks working 24/7. This is a troops relocation world so as long as you pump troops you can rebuild the army quickly with multiple villages.
2. You say they pull out 4 nukes in less than a day but how long have they been playing on this world? Do you know 100% that they didn't spend 2 weeks just storing up troops and just relocating it to their attacking villages once a nuke is wiped to get another quick attack in?
Based on your previous post, it seems like you are a pretty new player to this game so you may not have a full grasp / understanding of all the underlying mechanics.
