The harsh winter and the long battle will be great challenges for unlimited support of Europe for Ukraine.

Nearly six months since Russia opened a military campaign in Ukraine, the Western support for Kiev was still strong and quite uniform, surprised many people.

The German capital Berlin has turned off the lights, while the French stores are required to close when they are on the air conditioner if they do not want to pay a fine.

Ukrainian President Volodymyr Zelensky, who persevered in calling for the West to constantly aid to the country, it may be difficult to continue to attract the attention of European leaders when the conflict lasts.

The challenge for Ukraine is the same as the first day: keeping the West on their side when these countries face the expensive price because of the support for Kiev, not only the pressure of gas from Russia, but also Chi Chi.

It could be the reason why President Zelensky said that he wanted to end the war before Christmas, because the real problem would be how to make their promises in the long run, Giles said.

The winter fuel crisis is an obsession with European officials and diplomats every day, when Russia accounts for about 55% of the total imported gas of the continent in 2021. EU countries also need Russian oil.

The internal situation of the EU will be very difficult and we have to try to fulfill the commitment to prevent Russian profits from gas and other energy sources, a senior European diplomat said, mentioning the agreement.

However, this agreement is difficult to achieve the desired goal because it is based on voluntary.

Some Western European countries do not think that Russian energy dependence is a serious risk and they are even hoping to be able to return to normal relationships with Russia, Giles said.

European officials are also afraid that the strategy of weapons for Ukraine is now becoming a immediate solution to a long -term problem: it is a conflict with no end.

France, Germany and many European allies have provided Ukraine with many heavy weapons, helping Kiev block the progression of Russian forces in the East and open up counterattack opportunities in the South.

Good news is that these weapons are helping Ukraine.

In addition to economic and military expenses affecting the generosity of the West, there are also concerns that the world began to feel tired of the conflict.

In the rushing developments at the beginning of the war, the West is easy to make drastic decisions with Russia.

Luke McGee, CNN analyst, said that European countries would not simply withdraw support with Ukraine, but they would probably change the way.

Some Western European countries, especially Germany and France, publicly say that the West needs to maintain dialogue with Russia.

Do we have the same opinion about the ending of conflict?

The next few months will be the most difficult period for European countries since the conflict broke out.

In this context, it is difficult for political leaders to reasonably explain the money to support another country, especially when some people of their country can now feel they are generous enough, subdivision

Many Western officials say that at some point, European leaders may have to choose the best thing is to promote a peaceful agreement, gradually abandoning the script to end the conflict that Ukraine wants to repel back.

More and more concerned that if Ukraine was stuck and lost their advantages before Russia, calling for compromise acceptance would be stronger.

Fallon added that as soon as Europeans saw that Kiev showed signs of losing, they would start asking why we had to continue to provide expensive weapons for Ukraine in the middle of economic stress and why we

This is very important, because many key allies of Ukraine are facing domestic political issues.

When domestic political issues begin to emerge, people can ask why we help Ukraine instead of building infrastructure, Fallon said.

The effort to support Ukraine of the West, especially in Europe, may be much more difficult in the near future, according to observers.

Although most Europeans want to see that Ukraine achieved their goals and forced Russia to withdraw troops from the territory, their determination was not really challenging, the analyst Luke McGee said.
