Romania, the silent ally avoiding entanglement in Ukraine’s war

Bucharest is analyzing the wreckage of a possibly Russian drone on its territory, while maintaining a cautious approach towards Moscow following recent incidents near its border. […]

If an attack were to occur on Romanian soil, the country’s army is prepared to respond accordingly, says the Ministry of Defense. Bucharest is ready to deal with any Russian drone or missile that strays into Romania, but is also wary of escalating tensions.
