It’s hard for the Europeans to have a joint military operation there, because Article 11 of the Moldovan constitution explicitly states that “The Republic of Moldova will not admit the stationing of any foreign military troops on its territory”.

Even allowing unarmed European troops in would place the Moldovan government in breach of the constitution.

And the current government does not have sufficient power in parliament to unilaterally change the constitution.

If you wonder how the Russians can keep soldiers in Transnistria… that agreement predated the Moldovan constitution and was not replaced by the constitution.

According to Wikipedia, Denmark suffered the highest casualty rate per capita of any NATO country in Afghanistan.

If they gave Ukraine the long-ranged missiles needed to hit the launch sites and warehouses for these drones within Russia, then Iran’s exports wouldn’t matter.
