She did actually rhyme.

Or tried to.
But seriously, I like it. It’s rather simple but it has some real good metaphor to keep it form getting banal.
The rhyming is a bit forced and the flow a tad rough. But I like the structure and the rhythm of the poem.
Thunder, thunder, noisy crashes
Shouting, screaming, crying loud
See the lightnings, lots of flashes
Seems like time is running out
All the nations here together
But not to talk, no, just to kill
"Shot down children, ah, whatever.
We still have some graves to fill."
Love's an alcoholic drink
And we all are pretty sober
"I don't have the time to think!
I don't learn, I just do it all over."
If we would call peace a drug
We could say that we're all clean
"Those who died just had bad luck."
That's how it is and has always been.
The bold lines are where the flow is off. You could try to edit that.
And if you are going to edit you should also look at your punctuation.
It's a bit lacking.
But overall, good job. Simplistic but still a decent poem.
