Look we have a few more years till it catches up with ww2, and besides, the Shorter the war the more brutal it is.
Generally, the opposite is true. World War 2 left several belligerent nations as basically one large smoking ruin by the time it was over, but most successful coups involve just showing up in the right place before they know what's going on to force everyone to surrender before the fighting even starts.
During the 1954 US overthrow of the democratically-elected president of Guatamala, for example, US forces basically bumngled the invasion, but the threat of invasion was a powerful enough threat that the president fled, and the country was ruled by a long line of juntas with ever-growing anti-US resentment past that point.

On the other hand, it seems that the Abyssals can't actually invade anywhere besides various islands, so a lot of the casualties were probably dependent on how quickly and efficiently islands we evacuated (Polynesia, The Philippines, Indonesia, much of Malaysia, the Aletutians, Hawaii, and worst case scenario, the Carribean Islands), how effective the human counterattack has been, how much warning human detection systems give prior to attacks, and how many people fled the coasts. Honestly, if we're able to say that we're winning and can back it up, my guess is that it's been a (relatively speaking) low-causality war. Of course there have been casualties: soldiers, sailors, and civilians who refuse to leave their homes will always exist. But it probably isn't as bad as it could have been.

That depends upon how widespread Abyssals have been.
Arpeggio has the Fog Fleet stick strictly to the waters, but they absolutely crush all intercontinental travel.
Abyssals have aircraft and a willingness to use them. Although they're only displayed as using such against actual military targets like the naval base in the anime, if Abyssals have mastery of the seas, and carriers sitting of the coasts of the whole world, they could easily crush the vast majority of humanity that can't flee far enough inland to avoid the range of carrier-based aircraft.
That said, Abyssals are also seemingly more regional than Apreggio's Fleet of Fog. At least, nothing in the game leaves the Pacific outside of a brief foray towards Ceylon/Sri Lanka to follow the IJN's movements.
Hypothetically, there may be international fleets with a global coalition of shipgirls fighting to save the whole world, or maybe it's just the IJN shipgirls fighting in the outer reaches of IJN territory with a little help from post-war friend shipgirls coming in, there's no real indication of what's happening. There was an argument I was in earlier about how Iowa being loaned to Japan may be a sign that the United States is doing so well in their own war with the Abyssals, they can afford to loan a couple of their best out to an ally, while another was saying it was desperation that they were hoping that Japan would help bail out the United States in a losing war. Then again, there's also the chance that the majority of the world isn't fighting any sort of threats at all, and the Abyssals are strictly the ghosts of the Pacific War, alone, fighting against modern Japan, and Europe's still sitting pretty while Asia suffers.
Congrats! Fourth Anniversary!With all that short-term content that we've got, just getting to 4 years of continued service is worth congratulating!We've been getting more and more battles in the seas close to the mainland.And we're always busy with all those operations that've been bestowed upon us...Well, to be frank,Suddenly going all meta on me...But that's just a statement from HQ, right?And that they are recapturing control of the seas.According to the statement from headquarters, humanity is winning the war against the Abyssal fleet.How goes the war in general?That means we're into our 5th year fighting the Abyssal fleet.No... is it really something to congratulate?Congrats!4 years of Kancolle!
Congratulations!
