The Russian attack on Ukraine highlights the danger posed by private military groups

I'm about to board the first submarine known to have brought cocaine from South America to Europe. It is 20 meters long, carbon fiber and self-built.
After climbing to the top, I lift the manhole cover and descend into the hull, where three men survived 27 long days and nights as they traveled across the Atlantic Ocean. It is cramped, claustrophobic and extremely primitive.
Sunlight tries to penetrate through cracks in the walls of the submarine. You can understand why a captain took one look at the ship and concluded it was a death trap.
The heat and noise were intense as the engine at the back of the submarine burned through the 20,000 liters of fuel stored on board.
The crew of two Ecuadorian cousins ??and a former Spanish boxer set out from the Brazilian jungle and first traveled along the Amazon River. They had energy bars, cans of sardines and plastic bags that they used for toilets, writes the BBC.
That was about all they had. Apart from, of course, three tonnes of cocaine worth more than $150m (£121m).
But this was not a lucrative and stealthy mission carried out carefully.
The submarine's journey in late 2019 had been tracked by law enforcement agencies, including the UK's National Crime Agency (NCA).
After wrecking their ship off the Galician coast after running into trouble, the men were arrested and imprisoned. This piece of history in the fight against international drug trafficking is now a trophy in the car park of the Spanish police academy in Ávila.
However, it is not a rotting relic of a bygone battle: it is a symbol of a growing underground phenomenon.
Just last month, another submarine was discovered off the Spanish coast - again in the region of Galicia.
"For more than 20 years traffickers have been using submarines to reach Africa and Europe, but these two are the first we have caught," explains Antonio Martinez Duarte, Chief Commissioner of the Narcotics Brigade of the Spanish National Police.
"They are very difficult to detect," he admits.

Në fakt, mendohet se qindra nëndetëse të bëra vetë janë nisur drejt Evropës, e cila është tregu më i madh i kokainës pas SHBA-së, dhe një që po rritet me shpejtësi pas një rënieje të pandemisë Covid.
Madje thuhet se në mes të Atlantikut, rreth Ishujve Kanarie dhe Azores, shtrihet një varrezë masive e nëndetëseve kokaine, të fundosura qëllimisht pasi ngarkesa e tyre ishte shkarkuar me sukses.
Çdo mision i fshehtë do të kishte qenë një triumf i madh për ekipet e mekanikëve që ndërtonin në heshtje zejet e tyre në thellësitë e xhunglës së Amerikës së Jugut, kryesisht në Guajana dhe Surinam.
Megjithatë, në Spanjë, si pjesë e luftës globale të trafikimit, është policia që trumbeton një fitore të madhe në selinë e saj në Madrid.
"Ky është një operacion shumë i rëndësishëm," thotë kryekomisioneri Duarte. “Është hera e parë në Evropë që ne kemi gjetur më shumë se një ton e gjysmë bazë kokaine”.
Në fakt, oficerët thonë se ishte laboratori më i madh që e ktheu pastën e papërpunuar të kokasë në kokainë që ata kanë gjetur në kontinent. Por nuk është vetëm madhësia e ngarkesës e rëndësishme.
"Ky operacion konfirmon gjithashtu lidhjet midis kriminelëve kolumbianë dhe meksikanë që janë bashkuar me bandat spanjolle që punojnë në Spanjë," thotë kryekomisioneri Duarte.

Së bashku me nëndetëset, laboratoret e drogës janë një tjetër fenomen që po zgjerohet me shpejtësi.
Agjencia e drogës e Kombeve të Bashkuara thotë se prodhimi i kokainës u rrit me një të tretën midis 2020 dhe 2021, që ishte një rekord i lartë dhe rritja më e madhe nga viti në vit që nga viti 2016.
One place where they are witnessing first-hand the increase in the supply of drugs is in the port of Antwerp in Belgium.
Belgium's cocaine crisis is Europe's cocaine crisis and the UN is now warning that rival international gangs are working together like never before.
