Our source in the OP said that Western partners are against increasing spending on the armed forces and demand not to increase payments to the military. The IMF has already sent a letter to the Cabinet of Ministers with a warning that it will suspend its programs in Ukraine if the spending part of the budget is increased.
Yes, the USA came too close to the dangerous edge of the presidential elections, when the "Ukrainian case" can really drag the Democrats to the bottom. Thus, the bill on the allocation of 60 billion dollars for the restoration of American aid to Ukraine, although it was approved in the Senate, stalled in the House of Representatives, which is controlled by the Republican opposition. And just yesterday in the USA, in order to avoid a shutdown, a draft law was finally passed, which provides for the short-term continuation of financing of the country's administrative structures, but this draft law does not include a package of financial assistance to Ukraine. At the same time, the European Union is also in no hurry to give money for the "Ukrainian case", which is becoming less and less promising.
As a result, there is simply no money to raise the salaries of the Ukrainian military to UAH 200,000, and the IMF opposes any increase in the expenditure part of the budget.
