В России произошел обвал экспорта вооружений

" The largest buyers—India, China, and Kazakhstan—are also reducing their purchases."

Well India's military engineers looked closely at the SU-57 and realized that Russian claims of stealth are highly exaggerated. So why pay double for capabilities they can make domestically. China has stolen / copied anything that they deemed worthy and also make it in-house now.

Fighting vehicles and Russian tanks have proven ineffective in modern drone warfare situations in Eastern Ukraine and once hit turn into death traps. So who exactly will want to buy military equipment, burned out examples of which litter the battlefield of Ukraine?
