I'll say wat i said in the other thread.War is a business and many 1st world countries are earning more than you think from it.They get those modern weapons supplied from somewhere.They are probably as trained as any countries army or porbably more.
Remember that cartoon thing the french did a few months(or a year) back and then the French army doing **** in Gaza...i think that's the reason why Paris was targeted.Who knows maybe UK or USA is next.
