Simulation Strategy from Group 1

In our simulation, I was worried that our simulation would devolve into a war, like how the world went into WWI in 1914. To stop this, I was in country 1, so I wanted to make allies with the other strongest country, country 2. I thought that the best way to have security would be if everybody was allied together. Countries 1 and 2 wouldn't want to fight each other because there was no clear winner between a war between them, so nobody would invade us and we could be secure.
Also, because of group 1's economic and military power, we would have been able to discourage other countries from invading one another, which could have led to lasting peace. We were allied with groups 2 and 3, with 3 giving us general terms to our alliance. When group 5 proposed an alliance with my group, in exchange for help in what would be a war we would probably win, I accepted, as I saw that group 4 was not making alliances with any other group besides maybe group 3, group 3 probably wouldn't want to fight groups 1, 2, 5, and 6 combined, and I saw an opportunity to make alliances with every country besides country 4.
Once group 4 was destroyed, my plan was for country 1 to just keep accumulating power, make an alliance with group 6 as we already had a lot in common, and to stay friends with everybody. This would ensure a lot of security, as with everybody being in a common alliance, nobody would want to go to war with anybody else, as no one country would be strong enough to take on all of the other countries and we were already secure and had no need to invade one another. If one country made a move on another, I would expect everybody else to fight the aggressor.
The reason I joined with the war, and was willing to help with it, was because it helped secure our alliance with a side that would almost surely win, so we would be friends with all remaining countries. There was no actual reason for war for us, but it was advantageous to join in, and I think the war would have been avoided if country 4 had made an alliance with 1 or 2, as countries 3, 4, 5 or 6 wouldn't have wanted to potentially anger countries 1 or 2, and countries 1 and 2 didn't want to fight each other because neither side had a major advantage over the other.
