Estonia's foreign intelligence chief Kaupo Rosin says Russian President Vladimir Putin has few good options in Ukraine. His forces cannot advance significantly while Western sanctions are eroding resources.
Russia is losing more soldiers than it recruits in the fifth year of full-scale war. A general mobilization would be deeply unpopular.
Russia's economy contracted by 0.3% in the first quarter. Putin says government measures are yielding positive results.
Rosin says sanctions on the financial sector are hurting, and restrictions on oil exports are limiting income.
The spy chief notes no sign of a big breakthrough toward peace; Russia insists on Ukraine's withdrawal from Donbas.
Rosin predicts Russia will not abandon its goal of subjugating Ukraine while Putin remains in power, and will expand military along NATO's border.
