It's useless to argue.

All to no avail.

I tried in vain to persuade them.

It is not necessary to recount the consequences.

There is no use holding onto illusions.

You try straining it through cheesecloth, but it doesn t do much good.

I m trying to understand what is happening.

The feasibility of potential income generating activities has been tested.

But America s strategy has failed.

Such activities have proven to be successful.

And we're trying to tell them, It's not futile.

Sadly, his prediction proved correct.

Everything in between is virtually useless.

And I strongly believe that this is the choice that should have never emerged.

The facts have shown the opposite to be true.

Events are showing that to be so.

Sami searched for his children in Egypt but in vain.

But he had no working model to demonstrate the feasibility of these ideas.

Forces from the Allies attempted unsuccessfully to defend the islands.

Vietnam proved to be the end not the beginning of the line.

By and large, that prediction has proven to be correct.

Even the experiment with electronic voting machines was a qualified success.

The crisis proved that this was inadequate.

It was useless and it caused me a lot of physical and psychological pain.

Feasibility study on regional and subregional centres for capacity building and technology transfer

Two decades later, these efforts have proven to be a spectacular success.

The last few years demonstrate that neither approach will work.

Regulators proved unable to forecast and prevent the crisis.

The UN process worked. It was US policy that failed.

It has shown that it can defeat Georgia s army.

Only Einstein's theory proved to be consistent with experiments and observations.

That has proved very beneficial and will be continued.

Some have suggested that the Iraq war proved the UN s irrelevance.

But as a means to job creation there are questions.

This should be an integral part of any feasibility study.

The Iraq War proved costly to American soft power, with the US losing about 30 percentage points of attractiveness on average in Europe, including in countries like Britain, Spain, and Italy, whose governments supported the war. The recent photographs of detainees being abused and sexually degraded in Baghdad's Abu Ghraib prison added fuel to the fire.

But huge damage was done in 2001, when then Prime Minister John Howard s government refused to allow the Norwegian freighter MV Tampa, carrying 438 rescued Afghans from a distressed fishing vessel, to enter Australian waters.

Brazil has demonstrated the ability to be a technological export power.

Repeated studies have shown that well designed buildings are more comfortable.

These experiments clearly proved that the telephone could work over long distances.

Both the aircraft and the squadron proved adept at low level attacks.

There is no point in trying to win the hearts and minds of major drug traffickers.

Presumably, our attempt at resurrecting it was pathetic and hopeless.

And that means better, more meaningful responses when we search.
