It is not quite as clear cut as all that. On the same day Trump posted his threat on social media, the U.S. updated its bilateral strategic agreement with Poland, with both sides committing to “mutual self-defence and deterrence.” The U.S. still has around 10,000 troops in Poland and there is the prospect that, if some are removed from Germany, they could be re-deployed on Polish soil. President Karol Nawrocki has demonstrated strong sympathy and ideological alignment with Trump, which has helped the Poles deflect some of the ill-will coming from Washington.
