Russian President Vladimir Putin might use weapons of mass destruction, like chemical or tactical nuclear weapons, if he fails to gain a victory in eastern Ukraine, said a senior fellow at the Hoover Institute.

Ferguson told CNBC that if Russian forces are too tired to win in the next few weeks, Putin might find himself in a difficult situation.

There are two separate regions in eastern Ukraine where Russian and Ukrainian forces have fought each other.

Ferguson said that the situation with Russia and the United States on the verge of conflict is much more dangerous than most people realize.

Russia said it is at war with the West because of the economic sanctions it has imposed on the country.

Although I think we are not on the verge of World War III, we can still rule that out completely.

The U.K. Ministry of Defence said on Friday that Russian troops had fully withdrawn from the northern part of Ukraine.

The ministry said in an intelligence update that some units will be moved to the eastern part of Ukraine. Russia has engaged in military adventurism in the Donbas region for years, so Moscow is expected to shift its focus to that area.

The Russian units that were defeated by Ukrainian resistance are not expected to be redeployed quickly.

Many of these forces will require significant replenishment before being ready to deploy further east, with any mass redeployment from the north likely to take at least a week minimum, according to the British ministry.

Russia continues to shell cities in the east and south of the country.

Despite incontrovertible evidence to the contrary, Russia denies that it attacks Ukrainian cities.

Russia has suffered significant casualties in its invasion of Ukraine, according to the Kremlin spokesman.

It's a huge tragedy for us that we have significant losses of troops.

Ukrainian forces have surprised leaders and military experts around the world in their ability to push back on Russian military advances six weeks into the war.

NATO estimates that Russia's death toll could be as high as 15,000 troops, while Moscow last announced its casualty figures on March 25.

Ukrainian Foreign Minister Dmytro Kuleba has told NATO that the fighting in the east of the country will be similar to World War II.

The battle for Donbas will remind you of the Second World War, with large operations, maneuvers, involvement of thousands of tanks, armored vehicles, planes, and artillery. Many people will die, many civilians will lose their homes, and many villages will be destroyed because of this help coming late.

The German Marshall Fund of the United States' Jonathan Katz says that the current focus for NATO and its allies is to get Russia to end its war.

The less damage Russia can do, the more they can be isolated from the international system.

While countries cut economic ties with Russia, it's more important to get Russia to stop its violence and leave Ukraine, he told CNBC.

The UN voted to remove Russia from its seat on the Human Rights Council after reports of Russian troops raping, torturing and killing Ukrainian civilians.

According to a new report from the Economic Intelligence Unit, Asia-Pacific countries may be less exposed to the war in Ukraine compared with other regions, but they could still see less direct hits in areas ranging from commodities to tourism and weapons.

Russia and Ukraine are the main suppliers of some food commodities. Asia's high levels of dependence on energy and agricultural commodity imports will be a concern if prices go up.

Russia is the world's second-largest arms supplier and is a major source of arms for China, India and Vietnam, according to a research firm.

The report said which countries in Asia-Pacific would be least affected.

The Pentagon confirmed that all of the anti-air and anti-armor systems from the two packages that were announced in March have been delivered to Ukraine. The U.S. is trying to identify additional weapons systems to help the Ukrainian military, according to the Defense Department.

The Pentagon said that the Ukrainian President requested longer-range anti-aircraft systems.

More than 30 nations have sent assistance to Ukraine. According to the Defense Department, the U.S. has committed a lot of firepower.
