Which nation is most in need of a new flag

Turkmenistan.

The reason Turkmenistan needs a new flag is because their current one is too complex and difficult to reproduce.

You see, Turkmenistan is a country known for its ornate rugs and carpets.

So after becoming independent from the USSR, the new Turkmen Government thought it would make good national pride to include five traditional carpet styles onto their flag.

The problem was that putting 5 different carpet styles in a bar made the flag difficult to recreate in mass production.

So if most people in Turkmenistan want to look patriotic, they are likely to put up a portrait of their leader,

In a building,

In monuments,

In races,

Or Parades.

So yeah, if Turkmenistan wants to look less authoritarian, it would be best to have a simpler flag.
