Brussels: As it becomes clear that Washington's commitment to NATO and European security under US President Donald Trump is waning, the European Union is poised to intensify testing of regulations requiring the bloc's 27 member nations to assist one another in times of disaster.
Cypriot President Nikos Christodoulides told The Associated Press that leaders will work on "an operational plan" during a summit in Cyprus beginning later Thursday to maximise the use of the EU's military, security, trade policy, and other resources in times of need.

EU envoys will participate in "table-top exercises" in mid-May to practise how Article 42.7 of the bloc's treaties could be used to offer collective aid to a country in the event of an invasion or attack by a nation such as Russia.
A few weeks later, similar tests are anticipated to be conducted by EU defence ministers. The military, governmental organisations, or other relevant resources are not involved in the exercises, which are centred on political decision-making.
Similar to Article 5 of NATO, but not quite
An attack on one ally is considered an attack on all of them under NATO's Article 5 security guarantee, necessitating a collective response—often, but not always, through military means.It has only ever been used once, to help the United States after the September 11 attacks, which resulted in NATO's unsuccessful 18-year security operation in Afghanistan.
The EU's Article 42.7, which was written to prevent conflict with Article 5, has also only been invoked once, upon France's request in the wake of the 2015 terror attacks in Paris that resulted in over 130 fatalities and over 400 injuries.
According to an EU article, if a country "is the victim of armed aggression on its territory," its allies must offer "aid and assistance by all the means in their power."The paragraph allows for the neutrality of member nations like Austria and Ireland and stipulates that such assistance must be in line with the U.N. charter and not clash with NATO commitments.
When the United States is not present
EU countries extended assistance and showed solidarity with France's situation. In order to free up French forces for a significant domestic security operation, France urged its allies to intensify their efforts against international terrorism.
Over the previous ten years, similar activities to test the application of Article 42.7 have been conducted. However, mounting scepticism regarding the United States' commitment to NATO and the prospective EU membership of war-torn Ukraine has increased the urgency of the preparations.
Following Trump's threat to acquire Greenland, a semiautonomous region of the NATO member Denmark, recent contemplation on how Europeans might defend themselves gained momentum.
In a very symbolic show of support for Denmark, other European nations dispatched a small number of soldiers to the enormous island off the coast of Canada. Trump initially threatened to slap tariffs on participating nations, but he later changed his mind.
The planning appeared to be justified by Trump's willingness to go to war with Iran alongside Israel. A U.K. military installation on the Mediterranean island of Cyprus, which presently serves as the EU's rotating president, was the target of an Iranian retaliation attack in March.Choices and problems
The EU has access to a far wider variety of weapons than NATO, which is solely a security body. They include trade and visa regulations, border controls, sanctions, and military force.
In the upcoming weeks, as conflicts fester in the Middle East, drawing U.S. attention, and in Ukraine, the extent to which they and other measures might be utilised in times of crisis will be put to the test once more.Christodoulides told the AP, "We don't know what will happen if a member state triggers this article." "There are a number of issues."
