The politician believes that Russia is resorting to an "exhausting" policy in Ukraine, so the Western allies need not lose their resolve in supporting the Ukrainian side and be aware of the duration of hostilities.
“The UK and our friends must respond by providing assurances that Ukraine will have the strategic strength to survive and eventually win,” the prime minister said.
In addition, Johnson mentioned that the countries of Europe in the future need to direct resources to restore the destroyed infrastructure of Ukraine.
“President Zelenskiy’s government should pay salaries, run schools, deliver aid, and start reconstruction where possible.
This will require ongoing funding and technical assistance, which we need to plan for years ahead,” he said.
Earlier, the Prime Minister of Great Britain said on Sky News that the world is getting tired of the topic of Ukraine.
