There’s a lot of flags that annoy me and I would like to see changed, but I think these are the ones that I would change without a second thought:
Russia
Current: I find their current flag to be offensive to the eyes. The bright blue and red clash with each other, and the white bar at the top makes it looks like it's upside down. It gives off a very uncomfortable and depressing vibe.
Suggestion: I would change it to the old black, yellow, and white flag that Imperial Russia used. I think it's a very beautiful and elegant flag with a unique color combination that harmonizes well together.
Iran
Current: It takes the classical Iranian tricolors and gives them these disgusting squiggles to the green and red blocks that are supposed to be "Allahu Akbar" on repeat in the Kufic script. They also add this eyesore of an islamic emblem in the middle that supposed to be a bunch of swords and a crescent spelling out "allah" in Arabic. I don't know a single Iranian who likes this flag.
Suggestion: I would change it to the old lion and sun flag. Not only does it look badass, but this flag actually carries the history of Iran. It's the historical flag, it's the flag that people identify with, and it's a flag that encompasses all Iranians, not just the muslims (which are barely a majority in the country).
Iraq
Current: The flag of my home country is just stupid. It's a tricolor used by previous Iraqi flags with 3 stars in the middle. Saddam Hussein later added the words "Allahu Akbar" in Arabic between the stars. The new Iraqi government ran with it, but then later decided to remove the Saddam Hussein elements by removing the stars he didn't add and keep the "Allahu Akbar that he did add". It pissed off a lot of people because it's a deceitful attempt by islamists to pretend that Iraq is an islamic state.
Suggestion: Go back to the Qasim flag. This was a flag that was used in Iraq after the revolution to overthrow the monarchy. It used the pan-arab tricolors to represent the Arabs, a yellow circle that represented the Kurdish sun, and a red star that symbolized the star of Ishtar which represented the Assyrians in the country and the country's rich history. It's simply a superior flag, though I would do away with the pan Arab colors in favor of something that symbolizes Iraq.
China
Current: I will forever hold the opinion that communist flags are hideous. China is an ancient civilization that has a rich history and culture, and you're telling that they can't find anything to symbolize their nation outside of a foreign influenced communist flag? Bullshit.
Suggestion: Bring back the Qing dynasty flag. It's iconic, it's indigenous, and it represents China's deep heritage way better than a bland red flag with stars. Besides, it has a cool dragon on it, how can anybody hate that?
Belarus
Current: Is this not one of the ugliest flags in the world? The colors clash with each other, the blocks are not balanced, and the pattern on the side is just repulsive. Not only that but this flag is a stripped down version of the Soviet Imposed flag, which most Belarussians view as a symbol of Russian imperialism. To make matters worse the current flag was designed and imposed by Lukashenko, the brutal dictator of Belarus, in 1995. Belarussians view this gross flag as symbol of Lukashenko's tyranny and an extension of Russia's imperialism.
Suggestion: It's time to replace the current atrocity with the real flag of Belarus. Belarus literally means 'White Rus' as in the historical term for the ancient Slavic Rus who were never conquered by the Tartars, and this flag has a lot of white to represent that freedom and red for the sacrificing that it took to defend it. I specifically like the variation that has the coat of arms of Lithuania on it since a good portion of the historical Polish-Lithuanian Commonwealth encompassed modern Belarus.
I have yet to meet a single person from Spain who doesn’t despise him, even if they’re left wing
