And the world just blew me a kiss

First post entry for the comedy competition "my worst Christmas present" Please review

My Worst Christmas Present

My worst Christmas present was called peace and goodwill.
It turned up with the robins on my snowy windowsill
It woke me with a chortle, whipped me with a grin,
I said "I'm a weapons salesman, there's no need to rub it in"

"You've caused no end of trouble, do you think there's peace for me
When everyone loves everyone and Republicans hug trees?
Don't just stand there grinning, listen to what I say
I used to earn in millions till you turned up today”

“Ten thousand Kalashnikovs piled up in a heap,
Eight hundred stinger missiles just a rustin’ in the street.
My son’s in reconstruction, how do you think he’ll fare
If we haven’t bombed the HELL out of somebody somewhere?”

“When the homeless are building
The displaced founding
The lost returning
And the tables turning”

What the hell is in it for me?
