On August 15 local time, Polish defense minister bouashchak and visiting US Secretary of state pompeio signed the “enhanced defense cooperation agreement” in Warsaw. The agreement has been questioned both in Poland and abroad. The agreement signed on the 15th is an extension of the two agreements reached by Poland and the United States in 2019. According to the agreement, the mode of U.S. troops stationed in Poland will be changed from alternate to permanent, and the number of US troops stationed in Poland will be increased by 1000, that is, from about 4500 at present to at least 5500. The two countries have also reached an agreement on the location and use of seven military bases. According to the agreement, Poland will also provide free accommodation, fixed annual fuel costs, and part of the cost of weapons and equipment storage and the use of military facilities. Poland’s defense ministry estimates that Poland will pay 500 million zloty (about 935 million yuan) every year. The public opinion pointed out that the signing of the “enhanced defense cooperation agreement” between Poland and the United States this time, Poland has paid a huge price to attract more US troops, not only to bear the huge annual logistics support costs, but also to face the risk of sovereignty damage. Due to the fact that the text of the agreement has not been published to the public, the Polish Ministry of defense has made vague language in its press release on the issue of the legal status of the permanent U.S. Army, which is of great concern to all circles in Poland. In an interview, soloch, director of the Polish National Security Bureau, stressed that the agreement “does not have any extraterritorial issues”. However, several Polish media have bluntly pointed out in their reports that the US military will not be subject to polish jurisdiction. This situation worries all walks of life in Poland. David Jones, Professor of the center for American studies, University of Warsaw: the Polish people may be very reluctant to accept US troops stationed in Poland. If Polish people see that American soldiers can escape punishment after committing serious crimes, the US military should not be allowed to do so. As early as early as August, some Polish media disclosed that the Polish government would grant judicial immunity to the U.S. military stationed in Poland in order to reach the agreement, that is, the U.S. military personnel who violate Polish laws on Polish territory will be arrested by the U.S. military police and sent back to the United States for trial. After the report was published, there was public outcry, and all circles in Poland worried that this would damage national sovereignty. Defense Minister bouashchak then posted on social media, denouncing it as a false report, but did not make a targeted response and clarification. However, in the bulletin of the Ministry of defense on August 15, the issue of jurisdiction was deliberately blurred, leaving a huge space for moving.
