Why the DLU failed

The Union of Moderate Leftist Nations but more well known as the Democratic Left Union was an alliance of non-far leftist countries founded by Yugoslavunion,United Socialist Ecuador and Strczya.
It started out well however a Nation known as the Kremlinian Islands founded the Nova Kiev Pact which was a Marxist Leninist and other far-left ideology based Alliance. Kremlinian Islands made it clear that they were hostile to the Democratic Left Union
However rhetoric alone was enough for the DLU to declare war on the Nova Kiev Pact and the Pact Wars. The DLU's first mistake was jumping to conclusions and attacking the NKP and led to a series of bloody and ultimately senseless and unnecessary wars.
The first casualty on the DLU side was their ideology and belief as from then on the DLU was a purely military pact which did things that were contrary to their core values and that's the moment the DLU died and became something entirely different. By the time of the Caribbean wars the DLU was focused on military and Economic domination and had lost their way
After the Velestian collapse the DLU began to rot from the outside and deteriorated rapidly in the Communist Bloc and fled to the Union of Socialist Pact in hopes of growing a new base there. while members of that region did join it was not enough to save the DLU and the slow stagnating death came and the DLU died as a organization.
The DLU jumped to war on the basis of rhetoric alone and not action
The DLU put Economic and military superiority over their core values which led to them rotting from the inside
Their arrogance which led to the NKP crippling them
