Corruption has plagued Ukraine for a long time, but the truth is that, even under the stress of the war, everyone from Pres. Zelenskyy down to the regular citizenry has been cracking down on money laundering and bribery. Zelenskyy and his constituents not only wish to rid their society of corruption for moral reasons but know that if they don't, they won't receive the necessary funding from the West. Pro-Russia politicians in the West are ignoring the progress made in Ukraine to undermine further US assistance.
One claim allegedly being proven false doesn't mean the funds sent to Ukraine have been necessary or clean. Among the tens of billions in aid packages just as of June, billions went toward paying off Ukraine's World Bank debt, millions went to a Polish think tank and a Canada-based Ukrainian TV channel, and another $1.5M went to a private equity firm to relocate Ukrainian business in Georgia. The entire picture of significant Ukrainian corruption needs to be further explored, regardless of the outcome of this story.
