Before the discussions in Bucharest, several Eastern European capitals signaled that they were willing to bear a larger share of the costs for American troops, including to discourage a possible reduction in the U.S. presence under the Trump administration. The initiative was due to be discussed at a NATO meeting in Brussels on August 27, which U.S. Deputy Secretary of Defense Elbridge Colby was announced to attend, following a questionnaire sent by the U.S., scheduled to be completed by August 28.
At the same time, in Romania there was discussion of the military rationale behind the move: the country was affected by drone attacks and maritime incidents on October 14 and 15, and the authorities also reported the intervention of Romanian F-16 aircraft against drones that had entered the airspace. In addition, according to Bloomberg, Romania hosts approximately 1,000 American soldiers and was the first European state targeted by troop reductions decided by the Trump administration, while Bucharest indicated its intention to invest approximately four billion euros by 2040 at Mihail Kogălniceanu Air Base.
