The world's battle cry- writers block poetry contest week 1

The world has a discord between the left and the right.
Neither wants the other to rule, both want to fight.
Most are in the middle of the two extreams,
And realize the ends don't justify the means.

While the people fight about who's right and who is wrong
The leaders of the world sing a different song.
They have secret meetings, keeping people in the dark.
Adding fuel to the tinder, and waiting for a spark.

With enough propaganda and useful idiots
It won't take long before they get what they wish.
We need to find a song for the world's battle cry,
And kiss the global discord an overdue good-bye.
