[citation needed] Deshchytsia became a Candidate of Political Science after the successful defense of his master's thesis "The Rise of Multi-Party Systems in Poland and Ukraine", written under the supervision of Professor John-Paul Himka.

[10][11] On 27 March 2014, at the UN General Assembly, Deshchytsia presented the resolution on "Territorial integrity of Ukraine", which was supported by 100 United Nations member states, affirming the United Nations commitment to recognize Crimea within Ukraine's international borders and to condemn Crimea's annexation by Russia as illegal.

On 17 April 2014, Deshchytsia negotiated with John Kerry, Catherine Ashton, and Sergei Lavrov at a quadrilateral meeting in Geneva in an attempt to find a diplomatic solution to the war and humanitarian crisis caused by the Russian aggression in Ukraine.

However, Russia has repeatedly breached its commitments under the Geneva agreement, according to official statements of the leaders of the EU and the United States.

[14] In May 2014, Deshchytsia said: "The West should impose more severe sanctions that hit specific economic sectors such as banking and target Russian decision-makers.

[16] Deshchytsia also said "We expect that the decision (to switch to the 2nd phase of the introduction of a visa-free regime with Ukraine) will be taken at the EU Council's meeting on June 23".

Deshchytsia had descended on the protest in the hope that he could quell the escalating trouble, pleading with the demonstrators not to attack the building despite also understanding their concerns.
