These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: The Legend of Koizumi
Badass Decay: Oddly enough, George W. somehow went from "the 64th Gang Leader of Yale," aka "George of the Skull & Bones Society" (revealed in a Chapter 18 flashback) to the Butt Monkey of his first appearances. On the other hand, he got his ass kicked that time anyway.
This gets extra bonus points for managing to use the real-life dead little sister of the Bush family, Robin, in a completely tasteful and heartwarming manner.
And much earlier in the manga when Koizumi is trying to pull a Heroic Sacrifice.
Koziumi: Can you see me now, Grandpa? I've become... I've become a truly strong man.
Think about this for a moment: everyone in the Five-Man Band is a controversial figure in their home country. (Yes, even Koizumi.) But the writer is capable enough to make the audience cheer for them anyway, in spite of their shortcomings, not just because they're fighting the Nazis, but because they're genuinely likeable.
Evil Is Sexy: Skozerny, Ruddel, Rommel, Tristan and Isolde. Arguably, Yulia and Putin, before banding together along with the other good guys.
Genius Bonus: As this page shows, the series has sneaky Shout Outs for everything from Greek mythology to Dragon Ball to the Copenhagen interpretation of quantum mechanics.
Mengele vs Tymoshenko. Poisoning? Damn. Gonna die if it reaches your brain? Double damn. What do you do? YOU TAKE MENGELE'S SCALPEL AND SLIT YOUR THROAT TO BLEED THE POISON OUT.
And it somehow worked, without Tymoshenko bleeding to death.
A revolution on the moon? But who would be leading it? MOTHER FUCKING ROMMEL.
Les Yay: Tymoshenko and Eleonora come across as... quite a bit more than just friends. They've occasionally been described as a "D/s couple", but that isn't quite accurate since Tymoshenko would never willingly hurt Eleonora... or let anyone else hurt her, either.note There certainly is no question as to who "wears the pants", however, which is especially hilarious as Eleonora's Mildly Military outfit does include pants.
Moe Moe: Yulia Tymoshenko usually looks and rather acts like this; scarily enough this portrayal is not that far off the mark, which makes it even funnier. She uses this to more or less hide her Dark Action Girl side, which also is not that far off the mark from real life, minus the mahjong craziness. If she doesn't do it for you, though, her assistant Eleonora (who is one of the few manga-original major characters) pretty much exists to fill this trope, complete with glasses.
Never Live It Down: In the anime, at least, George W. Bush is razzed for several flubs from very early in his presidency, including the time he managed to fall off a Segway and the time he nearly died choking on a pretzel. The infamous shoe-throwing incident is also a source of ridicule.
This is all highlighted when we see him in bed, where he has a shoe next to his pillow, pretzels by his head, a Segway beside his bed, and a toy plane probably meant to suggest the infamous flight suit/"Mission Accomplished" debacle.
Followed by On the day of Rommel's death, the earthlight shone brightly on the moon.
After Skorzeny's death: "Return home Skorzeny. This world is full of corruption."
"It's a shame, Mr. Junichirou. If I had the ability to cry, those words would have reduced me to tears."
What Do You Mean, It's Not Symbolic?: Pretty much the Pope's style of play. In the words of one of the Vatican members, "Mahjong is man's attempt at recreating the Genesis. What happened to the universe in the beginning is happening on the Mahjong table."
