Well that's a bit of a false equivalency. Yes the war is costing billions in tax payer money and innocent lives, which is bad, but that isn't corruption. That's just a warmongering administration getting into and losing unnecessary wars.
All these random, relatively small, examples of corruption are sometimes uses of taxpayer money like in this case, but that isn't the problem - if the pool needed to be resurfaced then that is a legitimate government expense. It wasn't necessary, but that'd just be waste if we stopped there. The actual problem is the corruption - the facilitation of funding to the Trump campaign and Trump family, illegally, through pay for play schemes.
Both things matter, and obviously the war matters more as it has cost innocent lives, they are not the same type of thing though.
