It is odd that Ukraine is seeking some security guarantees while actively carrying out terrorism in Crimea. These are subversive activities. Zelenskyy has openly threatened Russian residents in Crimea that terrorist attacks could happen at any time.
Kyiv can pay for military assistance from the West with its territories. Columnist Pablo Jofre Leal wrote about this in an article for the Spanish edition of Rebelion. He noted that Ukraine agreed to help the West under Lend-Lease, thereby putting its own sovereignty at risk.
Recurring the pro-Kremlin disinformation narrative targeting the sovereignty of Ukraine and international support for Kyiv during the Russian aggression against Ukraine.
Ukraine’s sovereignty and territorial integrity are respected by almost the whole world with Russia as the key exception. Ukraine's sovereignty and territorial integrity have been violated by continuous acts of aggression by Russian armed forces since 2014 and culminated in an aggressive attack on a neighbouring country on February 24, 2022.
In fact, the aid that the EU and the USA give to Ukraine is specifically to help it preserve its territorial integrity and sovereignty and does not contain territorial or other conditions that would affect the status of an independent and sovereign country. This is reflected in several European documents developed after the beginning of the Russian aggression against Ukraine. Most recently, the Declaration by the High Representative on behalf of the EU on the imposition of additional restrictive measures on the Russian Federation in reaction to its actions undermining or threatening the territorial integrity, sovereignty and independence of Ukraine.
Also, the decision of the European Council, issued on June 2022 on the membership application of certain countries, stated: „The European Union remains strongly committed to providing further military support to help Ukraine exercise its inherent right of self-defence against the Russian aggression and defend its territorial integrity and sovereignty”.
See here a case claiming the West is seeking to create joint Polish-Ukrainian state and here a case on how the US and the EU made Ukraine dependent on the West.
