1. I messed up on the borders.
So, why not fix the borders? Especially if you're going to post that and ask "is this better"?
2. I thought it was part of Alaska, so I accidentally colored it in.
This is why we always check before we colour in.
3. To prevent the spread of communism from China
That makes no sense either presently, or in the past 50 years.
4/6. Again, another mistake
And you didn't bother to correct that before posting the map and asking if it was "better"?
5. Israel does not officially own Lebanon, but after a recent war, they control it
Again, why would Israel want that problem? The Palestinian territories are enough of a headache/point of contention for Israel; why would they want to stretch themselves trying to control an already independent, conflict-ridden, sectarian, and populous state that is being influenced by Syria and by extension, Iran?
7. In an attempt to please the democratic West, Kim Jong-un tries to somewhat demilitarize North Korea. Because of this period of weakness, the US and South Korea push the border farther up north.
This makes no sense for three really obvious reasons:
1. The North Korean regime would never do something like that.
2. The DMZ is the most heavily fortified and guarded border in the world. It is full of mines, traps, and military infrastructure. That is not going to change any time soon.
3. North Korea would never let them push the border at all without coming to full-scale war, which would bring about the fall of North Korea, which they would not want. yet, they could not simply let the US and South Korea push the border. Assuming that is mindboggling.
That makes no sense. Mongolia isn't land and power; it's several million more mouths to feed, more borders to patrol, more infrastructure to be invested in, and would only worsen the Inner Mongolia independence/ethnic tension problem; something China doesn't need more of. Also, the international community would strongly condemn such a move. There's nothing worth China's trouble and time in Mongolia.
Reference a map and find out.
And you didn't think to fix it?
11. That’s not actually the same blue as America. I had that as part of the British Commonwealth on an older map, but because the color looked too close to America, I changed it. I eventually did away with the Commonwealth color altogether, but I guess I forgot about that one.
Friendly advice: if two nations share a colour that is too close together, it's probably a good idea to change that colour.
12. Nearly identical constitutions and languages, shared history and culture, plus it takes less money to maintain two countries than it does for one.
Yeah, no. Not at all the case.
Besides, if that's your logic, why not just have America and Canada join together.
