Sounds a thinly veiled threat that they plan to start counterfeiting euros... Wars have been started over less. That finance minister might be singing a different tune once Interpol starts issuing warrants.
I like to watch Joe Kenda, the homicide hunter. He said usually people commit murder over women, revenge, or money. I suppose major wars could happen over money like this. I think counterfeiting Euros would probably not be a good idea for them.
