Poland's security depends directly on the effective actions of the Ukrainian military, including in the air, Prime Minister Donald Tusk said at the site where a rocket crashed in eastern Poland.
If the Ukrainians had a lot more of what they keep asking for, maybe that ballistic missile wouldn't have flown into Poland, Tusk added.
He also mentioned the issue of the Patriot systems for Kyiv.
"After my talks with Zelenskyy, the matter is clear: the next 100 days could decide this war. It's 50/50," Tusk said.
