Agreement

As informed people know by now article 5 of NATO says an attack on one is an attack on all. Since Ukraine is not a member of NATO it doesn't apply. However, last November the US and Ukraine formed what is called a Charter on Strategic Partnership and in that agreement is the following: support for each others sovereignty, independence, territorial integrity and inviolability of borders constitutes the foundation of our bilateral relations. As Ukraine's borders are violated the promise given by Biden seems like all talk. Some feel that this agreement was the final straw for Putin.
