Not long ago, the situation in Ukraine could have been characterised as a stalemate. Today, the situation for the defenders is worse, with Ukrainian positions along long sections of the frontline. Russian troops are , and concern is building that they might be able to break through.

While not yet gamechanging, these advances indicate that Russia can move forward 鈥 and still intends to win the ground war. Backed by aircraft and guided bombs, Russian troops can put pressure on Ukrainian forces, who are overstretched by .

Admittedly, what Russia has been able to accomplish so far doesn鈥檛 feel much like winning. They have recaptured some important territory, though the price paid has been ruinous.

The capture of Avdiivka alone cost Russia . Still, stopping these advances from turning into breakthroughs is costly for Ukraine as well, and despite these losses, Russia is still massing forces for further offensives.

The nature of the frontline is challenging. The presence of drones is increasing the lethality of artillery and making movement difficult.

Both sides are dug in, with extensive networks of trenches and minefields around key locations. Ukraine has done well to hold on but is now approaching a critical moment. Their forces are stretched thin across an extended front line, their western-supplied weapon systems , and a shortage of munitions 鈥 - makes it difficult to react to Russian movements.

Ukrainian difficulties on the front reflect wider challenges. The nation is struggling , with insufficient available to shore up the frontline. As the war drags on, morale is under increasing strain, with taking a toll.

Ukraine鈥檚 president Volodymyr Zelensky signed a bill into law on April 2 which from 27 to 25. And the Ukraine parliament to overhaul the country鈥檚 system of mobilisation, but details of what the new law will do remain unclear.

But the key will be providing Ukraine鈥檚 armed forces with the weapons it needs to continue the fight. Kyiv needs solutions to Russian air power, ideally in the form of systems, as well as more artillery and missiles.

Some of these assets are becoming increasingly hard to acquire, however. Donor nations are contending with their own , and production is still well short of what is needed on the frontlines.

Both Europe and the US are stepping up their arms production, but this will take time. Recent windfalls, such as the shipment of sent to Ukraine by the US are helpful, but a consistent supply is harder to secure.

In addition to production problems, the political will to back Ukraine is fading. Support for the war has moved from a broad international consensus into a contentious political issue in both Europe and America.

While Ukraine still has vocal supporters around the world, aid packages are becoming more difficult to secure. This was in February. And while the Biden administration is still to get weapons to Ukraine, it has to contend with other international conflicts and mounting domestic pressure.

A recent shows how controversial the issue of Ukraine funding is becoming. The looming US election will undoubtedly , particularly given the prospect of a second Trump presidency.

The Washington Post on what it called Donald Trump鈥檚 secret, long-shot plan to end the war in Ukraine". This, the newspaper report said, would involve 鈥減ushing Ukraine to cede Crimea and the Donbas border region to Russia鈥.

For their part, the Russians are adapting to the nature of the war. The Putin regime remains in control and has the backing of , according to a poll taken on February 6.

Moscow can out-conscript Kyiv and accept severe casualties with greater ease. Its economy is shifting to reflect its commitment to a long war, and it has developed workarounds to .

A steady, supply of equipment is ensured through its and . Russia has capabilities that Ukraine do not, and it is figuring out how to use them. As a result, it has been able to take the initiative.

By summer, Russia will be able to bring its force to bear. It has already begun shaping the battlefield, attacking Ukrainian positions with in preparation for further major attacks. They have massed significant ground forces, certainly enough to present a problem for defending Ukrainian troops.

But Russia will be unable to sustain the offensive for long 鈥 particularly if they keep at their current rate. The situation on the ground doesn鈥檛 lend itself to advancing, and Russia is experiencing many of the problems that the .

On top of this, they are still making costly mistakes. A recent major attack north-west of the recently captured city of Avdiivka in the Donetsk region was 鈥 reportedly with .

But this is no reason to be complacent. Looking at other campaigns particularly their , it is possible to suggest that while Russia is willing to fight long and costly wars of attrition, the . This is what distinguishes Ukraine from the wars Russia has fought within its own territory. Both Europe and America need to understand that failure to adequately support Ukraine could have disastrous consequences.
