Unfortunately arms dealers operate very freely in all areas.
If you want to play on a frightening database,
www.nisat.org has one where you can select a country like Poland, and see how much they earned from arms sales and in which directions the arms went...
I have had the dubious honour of attending arms fairs held in the UK in recent years and it is frightening to see who the sellers are and try and guess who the buyers represent.
BTW - I am not and have never been involved in the manufacture, use or sale of weapons, I was only there providing first aid cover in case anyone dropped a shell on their foot.
