There are many wars in Europe. Some of these are older, while others are more recent and modern. Religion was a major cause of European wars. There were also conflicts due to the Soviet Union's threats. These wars took place in both Europe and Asia. You can read more about them here.
Europe's primary cause for war was religion
The early modern era is the beginning of the history of religion and warfare. In Europe, wars were often fought over religion. Religious conflicts drew the attention of the public, and they were followed closely, leading to the creation of a multitude of publications to provide real-time coverage.
Wars of religion were often fought between neighboring countries and between foreign powers. They targeted entire populations and left tremendous collateral damage. These conflicts generally affected the common man. During the Thirty-year's War, for instance, mercenary troops pillaged villages and destroyed properties.
Transatlantic cooperation
The United States and Europe used to be allies. However, recent terrorist attacks have shown that their transatlantic relationship is less secure. Europe will struggle to maintain its military relevance in Washington, as the United States is primarily focused on international terrorism. To remain a trusted and influential partner in America, Europe must make major changes.
It is important to have a constructive transatlantic partnership in order to avoid a second war in Europe. Washington and Europe both believe in maintaining the transatlantic alliance despite differences. Transatlantic cooperation will only work if allies agree on key global issues. However, Europeans may be wary of Washington's openness to constructive criticism.
Soviet threat
The Soviet threat to Europe wars is real. This should not come as a surprise. The Soviet Union's nuclear capabilities have significantly increased since the Cold War. They are now more powerful than NATO's. In fact, the Soviets have become the major player in conventional war in Europe, with NATO outnumbered by nearly three to one in artillery, anti-tank guns, and air defense systems. The Soviet Union developed its mobile SS-20 rocket, with a range exceeding 5,000 kilometers. This missile can strike in minutes and reach every corner of Europe.
During Cold War, the USSR was polar opposites to the United States, and they had mutual distrust of each other. In the 1970s, Soviet leaders and American leaders began to negotiate and sign strategic arms limitation agreements. Brezhnev declared that peaceful coexistence is the norm in 1973, but warned that wars could still break out in Third World.
The Impact of Nuclear Weapons
It is vital to understand the consequences of nuclear weapons for Europe's security, in a world with increasing nuclear threat. Their use can have devastating consequences. As the Non-Proliferation Treaty Conference draws near, policy-makers try to keep up with rapidly evolving nuclear threats. As a result, the arsenals of nuclear-weapon countries are increasing. Iran, for instance has an estimated breakout time of less then a month. The Iranian nuclear deal was canceled by the US president, which has increased the danger.
Many European nations considered developing nuclear weapons after the Second World War. Some even began nuclear weapons programmes, including Sweden. Recent research showed that the country is closer than many thought to have nuclear weapons. Germany's government was also open to the possibility of building a European bomb with France and Italy. In reality, Germany's defence Minister Franz Josef Strauss secretly signed a contract with his counterparts Paris and Rome.
