Since Voldemort used strong tactics to temporarily control the International Federation of Wizards, his every move has been monitored by the Ministry of Magic in various European countries. Although no one is willing to provoke such an unkillable monster, no one is willing to let their country become as bad as the United Kingdom. Of course, they were able to say such a thing because they saw that Voldemort did not have enough manpower to control a country. Only the Ministry of Magic, represented by France and Germany, had time to say it.
