Are US Drone Assassinations, Both An Declaration of War And An Act Of Terrorism?

The news that Iran General Qassem Suleimani killed in Baghdad drone strike ordered by Trump, is highly disturbing. It is surley a declaration of  War .

It bears the question to what extent this is an assassination and what is the difference between a drone attack by a nations military on the orders of their  elected leader and a terrorist bomb planted by a illegal organisation?

The Guardian reports that

The White House said Donald Trump ordered an air strike that killed powerful Iranian general Qassem Suleimani in Baghdad in the early hours of Friday, in a dramatic escalation of an already bloody struggle between Washington and Tehran for influence across the region.
Suleimani, who ran Iranian military operations in Iraq and Syria, was targeted while being driven from Baghdad airport by local allies from the Popular Mobilisation Units (PMU). The deputy head of the PMU, Abu Mahdi al-Muhandes, a close Suleimani associate, was also killed in the attack.
“General Suleimani was actively developing plans to attack American diplomats and service members in Iraq and throughout the region,” a Pentagon statement said. “This strike was aimed at deterring future Iranian attack plans. The United States will continue to take all necessary action to protect our people and our interests wherever they are around the world.”US troops deployed to Middle East after Baghdad embassy siege
Minutes before the statement Trump tweeted a US flag without comment. Later, the White House put out a statement saying the strike was a “decisive defensive action” carried out “at the direction of the president”.

Iran’s supreme leader, Ali Khamenei, ordered three days of mourning and vowed that the US would face “severe revenge” for the killing.
The Iranian foreign minister, Mohammad Javad Zarif, said on Twitter: “The US’ act of international terrorism, targeting & assassinating General Soleimani – THE most effective force fighting Daesh (ISIS), Al Nusrah, Al Qaeda et al – is extremely dangerous & a foolish escalation. The US bears responsibility for all consequences of its rogue adventurism.”
US secretary of state Mike Pompeo posted a video he said showed Iraqis dancing in the street “thankful that General Soleimani is no more”.
Suleimani was commander of the Quds Force, the elite, external wing of the Iran’s Islamic Revolutionary Guard Corps (IRGC), which the Trump administration designated as a terror organisation in April last year. The Pentagon statement claiming responsible for the strike accused the Quds Force of being responsible for the deaths of hundreds of US service members and the wounding of thousands more.
Many consider Suleimani to have been the second most powerful person in Iran, behind Khamenei, and arguably ahead of President Hassan Rouhani. Through a mix of security operations and diplomatic coercion, has been more responsible than anyone else for projecting Iran’s influence in the region.

 The escalation had followed a tit-for-tat series of strikes by both sides, which have been protagonists in Iraq since late 2006. Suleimani had been central to almost all that Iran did and was considered by senior officials under Barack Obama as being close to untouchable.The strike came at a time when Iraq was already on the brink of an all-out proxy war, and hours after a two-day siege of the US embassy in Baghdad by a mob of PMF militants and their supporters. The Pentagon accused Suleimani of having masterminded the mob attack.That siege followed US air strikes on camps run by a PMF-affiliated militia particularly closely aligned with Tehran, which in turn was a reprisal for that militia’s killing of a US contractor in an attack on an Iraqi army base on Friday.
The US has deployed 750 airborne troops to Kuwait as a rapid reaction force available for use in Iraq, and officials has said up to 3,000 could be sent in the coming days. The defence secretary, Mark Esper, said on Thursday that more militia attacks were expected and the US reserved the right to take preemptive action to stop them.
“There are some indications out there that they may be planning additional attacks,” Esper said. “If we get word of attacks, we will take pre-emptive action as well to protect American forces, protect American lives. The game has changed.”
Suleimani’s death leaves Iraq and the region on the brink of a new upsurge in violence, with Trump’s and Khamenei’s moves and counter-moves hard to predict.
Trump ordered the strike at a time when the US Congress was in recess, and the White House framed the action as an act of self-defence in the context of counter-terror operations. But Democrats and perhaps some Republicans in Congress will see it as an usurpation of the legislature’s authority to decide matters of war and peace.
“One reason we don’t generally assassinate foreign political officials is the belief that such action will get more, not less, Americans killed,” Democratic Senator Chris Murphy said on Twitter. “That should be our real, pressing and grave worry tonight.

The whole issue of Drones and targeted  assassination, which does not to me seem any different in sending agents in another country and "removing an enemy" in the manner  that Russian former double agent Sergei Skripal and his daughter were poisoned with a military-grade nerve toxin that had been left on the front door of their home in England, British counter-terrorism police said.

After the first known offensive use of a chemical weapon on European soil since World War Two, Britain blamed Russian President Vladimir Putin for the attempted assassination and the West has expelled around 130 Russian diplomats.

I can't see how anyone can condone both.

As far as I know there has been no declaration of War between the USA and Iran and should we condemn both Trump (and indeed those carried out under Obama ) assassination by Drone in the same way Putin sends gents to remove his political enemies.

This is very likely to see an increase in terrorist attack , whether sponsored by Iran or not.

We musnt  ever forget The September 11 attacks ( against the United States on the morning of Tuesday, September 11, 2001. The attacks resulted in 2,977 victim fatalities, over 25,000 injuries, and caused at least $10 billion in infrastructure and property damage.^[6][7] Additional people have died of 9/11-related cancer and respiratory diseases in the months and years following the attacks. 

 But the response afterwards and the understandable  calls for revenge , has seen the wrong targets chosen and the role Of Saudia Arabia , in backing terrorist organisations  seemingly ignored.

We seem to be entering a period where war is carried out not on the battlefield but by drones sent from far away and terrorists  incidents.

In all this the major casualties are likely to civilians.
